Rather than having to track which bit in which register should be
cleared or set to gate or ungate the clock to a certain peripheral,
provide a simplified enum which encodes the register and bit. This
change comes with a function which decodes the enum and gates/ungates
the clock.
This also removes the register-dependent bitmasks for APB0 and APB1
gating registers.

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: 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 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.
