mainboard/msi/ms7d25: Add early support for MSI PRO Z690-A DDR4 WIFI

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.
