The end of the _PS0 method that is supposed to transition the
XHCI device to D0 state is instead putting it in D3 state.
This triggers a PME_B0 GPE which causes a Notify to the XHCI
ACPI Device in the kernel and that increments the wakeup counter
and causes aborted suspends.
Instead if we just leave the device in D0 where it should be
after executing this function then the PME_B0 is not generated
and the kernel does not see a wakeup on XHCI.
Similarly I changed the _PS3 method to always put the device in
D3 at the end of the method, rather than depending on the state
to be D3 at the start.
Before this change the kernel would see the following sequence
when trying to suspend when the XHCI controller is in D3cold:
kernel: ACPI: Execute Method [\_SB_.PCI0.XHCI._PS0] (Node ffff88017802bf28)
kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [XHCI] (Device) Value 0x02 (Device Wake) Node ffff88017802bc30
kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [EHCI] (Device) Value 0x02 (Device Wake) Node ffff88017802b8e8
kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [HDEF] (Device) Value 0x02 (Device Wake) Node ffff88017802b1b8

kernel: PM: Wakeup pending, aborting suspend
kernel: last active wakeup source: 0000:00:14.0
Now it does not get a notification (due to PME_B0) when going to D0
on the way into suspend. XHCI goes from D3cold to D0 (in order to
be able to read mmio) and then back to D3hot before suspend.

The coreboot and ACPI code that clears USB3 PORTSC change status

which would disable the port.
Additionally add back the code that resets disconnected USB3 ports

clear the PME status bit so we don't immediately wake.

The recommended value in docs is D2, but lynxpoint XHCI does not even
support D2 state which causes the kernel to think this device cannot
be used as a wake source:
kernel: xhci_hcd 0000:00:14.0: System wakeup enabled by ACPI
kernel: ACPI: Device does not support D2
kernel: xhci_hcd 0000:00:14.0: System wakeup disabled by ACPI
Additionally this means the kernel will never put the device into D3
state by itself. There is SMI code that will put the device into D3
before suspend so advertising D3 here should be correct.
With this change the kernel will put the controller into D3 on suspend
and back to D0 on resume, including executing the ACPI methods
for _PS0/_PS3 that contain chipset specific workarounds.
In addition add a _PSC method to directly return the D state from the
device registers. With ALL USB devices removed the XHCI controller
goes into D3 state and the kernel can have a hard time determining
the state of the device at boot.
A kernel compiled with CONFIG_ACPI_DEBUG=y and module parameters
acpi.debug_layer=0x7f acpi.debug_level=0x2f can be used to see
what ACPI methods are executed:

This commit adds a new Kconfig option for the LynxPoint
southbridge that will have coreboot route all of the USB
ports to the XHCI controller in the finalize step (i.e.
after the bootloader) and disable the EHCI controller(s).
Additionally when doing this the XHCI USB3 ports need
to be put into an expected state on resume in order to make
the kernel state machine happy.
Part of this could also be done in depthcharge but there
are also some resume-time steps required so it makes sense
to keep it all together in coreboot.
This can theoretically save ~100mW at runtime.
Verify that the EHCI controller is not found in Linux and
that booting from USB still works.

This re-factors clock_get_periph_rate() to be a simpler and also
make a few corrections along the way. To summarize:
- clk_bit_info is no longer used. It had numerous errors and was
really painful anyway since it was just a bunch of opaque magic
numbers that made bugs non-obvious.
- Clock source bitfields for peripherals handled in the switch
statement are 3 bits, not 4. Some divider values are 3 bits,
some are 4. The earlier code always assumed 4 bits for both
which included reserved bits in many cases.
- UART source clock and divider shift values were wrong.
- PWM clock divider was being read from the wrong register.
- SPI3 divider value was being read from the wrong register.
- There was a really confusing calculation for SDMMC0 and SDMMC2
clock rates, but it was never actually used since the switch
statement never handled PERIPH_ID_SDMMC{0,2} and would thus
return if they were ever passed into this function.

ports were configured in the same fashion, but there are a few
exceptions.
For example, the inner function runs differently if we're using 8 bits

requires SD_0_CDn to be an output rather than alternate function and
must have a value set.
This patch trades some verbosity for simplicy. Now the SDMMC GPIO

This includes the new dp code, which is better, and the fimd code,
which is changed and improved. We took the chance to remove un-needed
files, and also to remove some foolish u-boot habits, but not all of
them. That will take time.
With these changes we get graphics.
Since the only mainboards we have with 16 bit graphics are 5:6:5,
adjust edid.c to just use that format. If at some future time we need
4:4:4, which seems unlikely, we'll need to add a function to adjust
the lb_framebuffer. Note that you can't just divine this from the EDID,
as the graphics pipe format need not match the actual final format used.
The EDID reading works. We've been requested to support hard-coded
EDIDs and that will come in the next revision. Currently the hard-coded
EDID is ignored for testing.

In a previous commit the contents of wakeup_need_reset were removed because
the GPIO it referred to wasn't connected to anything on pit. I didn't realize
at that time that that could have been because we hadn't tried getting
suspend/resume working on pit and hadn't updated that file. On snow, the GPIO
is the recovery mode pin. This change updates pit to have the right GPIO,
kirby to read that GPIO, and makes the comments for both pit and kirby more
explicit and spells out the fact that this is the recovery mode GPIO.
Having a check here at all may still be a holdover from snow that isn't
applicable to pit or kirby, but since there is a parallel as far as the
recovery mode GPIO we might as well make them match while waiting for more
information.
