CLKOUT for PCIE ports 1-5 and CLKOUT_XDP are not used

I couldn't test this directly without a scope so instead I
used a modified commit that also disabled PCIe Port 0 and
saw that that correctly disabled the WLAN port.

The original ME code was assuming that the only type of messages
it would send were MKHI type and so it had some embedded checks
for that header and that type of message.
In order to support ICC messages this needs to change to handle
different header types, so now the header will be sent first
and then the data will follow, rather than the two both being
sent in the same low-level function.
This change has no real affect on the system, subsequent commit
will add new ICC messages.

When the EC requests the host to throttle (for charging or thermal

Right now this is set at 12W but that is somewhat arbitrary and may
need tuning.
1) define the THRT method in \_TZ scope for EC to call
2) enable SCI events for throttle start and stop
3) define the power limit at 12W and set it in NVS
1) Enable CONFIG_ACPI_DEBUG=y in the kernel
2) Enable the Debug object event in acpi module
acpi.debug_layer=0x7f acpi.debug_level=0x2f
3) Using EC console generate host event for throttle start

An issue was observed using a specific vendor's TPM in that it
chokes on access to registers that are not explicitly defined in the
PC client specification. The previous driver used generic access
functions for reading and writing registers. However, issues come
to play when reading from the status register. It read it as a 32-bit
value, but that read address 0x1b which is not defined in the spec.
Instead of using generic access functions for the tpm registers
provide explicit ones. To that end provide more high level wrapper
functions to perform the semantic access required.

The EHCI driver defines a maximum transfer timeout of two seconds. The
comments state that during tests the maximum amount of required transfer
time was for the SCSI TEST_UNIT_READY command on certain devices. We
have now observed a USB device (Patriot Memory 13fe:3100) that can NAK
this command for slightly more than two seconds. It will also completely
fail if the timeout hits, since it gets confused by the subsequent CSW
retry/recovery mechanism and starts producing babble errors. This patch
increases the timeout to three seconds to circumvent this problem.
To test, boot a Falco from a red-black RageXT USB stick.

The management engine is slow, requiring at least 500ms between
when the Dram Init Done message is sent (right after memory training)
to when the MBP will report that it is successfully cleared and
that the ME can finally be sent the EOP message.
Currently this is adding 100-150ms to the boot time. If we defer
waiting for the MBP Clear indicator until the finalize step we
can gain back that lost time.
boot on falco with SMI debugging enabled to
ensure that the ME is locked down in the finalize step:
Finalizing Coreboot
SMI# #0
SMI_STS: PM1 APM
ME: MBP cleared
ME: mkhi_end_of_post

There are specific programming requirements for the usb3 ports
on all LynxPoint chipsets when transitioning to D0 or D3.
LynxPoint-LP has additional workaround steps needed involving
resetting the disconnected ports when transitioning to D0.
The workarounds are implemented in ACPI code so the controller
can transition properly into D3 at runtime.

This reverts commit ff81f50f0e4c068b64c4a5c7f5244196ecd24965.
Deferring this step until the finalize stage will allow us
to defer waiting for the MBP clear indicator and speeding
up the boot.

The intel_ddi.c change I thought should be in but I don't see it. It just adds two functions back
that we need.
There are two new files for slippy annotated with comments about how it needs to evolve.
That said, this code has been tested on 3 different panels. Both dev and non-dev usages work.
physbase initialization to static value removed.
Moved spin calls to intel_dp_*

Peppy SPD table has 4GB configurations followed by 2GB configurations.
Current implementation does remapping to point 2GB configuration to the
same SPD index as the 4GB. This is different than Falco, which simply
duplicates the SPD data for all configurations. To simplify probing in
mosys, copy the Falco implementation of duplicating SPD data.

When using RW firmware path the proper recovery reason can
be retrieved from the shared data region. This will result
in the actual reason being logged instead of the default
"recovery button pressed" reason.
1) build and boot on falco
2) crossystem recovery_request=193
3) reboot into recovery mode, check reason with <TAB>
4) reboot back into chromeos
5) check event log entry for previous recovery mode:
