Original firmware ships with PTT enabled by default on poweron.
PTT takes priority over SPI/LPC TPM so enable the CRB interface
until coreboot implements a way to select the interface and adapt
the API to handle any TPM detection.
TEST=Boot the board and see PTT is detected by Windows and Linux

Add the full PCIe root port configuration. Proper initialization of
the root ports depends on the correct GPIO programming including
virtual wires. Do not program the CLKREQ signals in coreboot to let FSP
detect and configure CLKREQ pads. Otherwise the CLKREQ pads are
reprogrammed by FSP despite having GpioOverride=1. The pads that
should not be touched by coreboot are left commented in the board GPIO
file. CLKREQ reprogramming caused undefined behavior when ASPM and
Clock PM was being enabled by coreboot on PCIe endpoints of CPU PCIe
x4 slot (coreboot printed a lot of exceptions and simply halted).
TEST=Boot the MSI PRO Z690-A DDR4 WiFi with all PCIe/M.2 slots
populated and check if they are detected and functional in Linux.

Initial mainboard code MSI PRO Z690-A DDR4 WIFI. The platform boots up
up to romstage where it returns from FSP memory init with an error.
What works:
- open-source CAR setup
- NCT6687D serial port with TX pin exposed on JBD1 header
- SMBus reading SPD from all 4 DIMMs
This board will serve as a reference board for enabling Alder Lake-S
support in coreboot. More code and functionalities will be added in
subsequent patches as src/soc/alderlake code will be improved for
PCH-S.
TEST=Extract the microcode from vendor firmware and include it in the
build. The platform should print the console on the serial port even
without FSP blob.
