soc/amd/stoneyridge: use SoC common uart ops
Define the UARTs as MMIO devices in the chipset devicetrees. Drop ACPI
_STA in asl since now handled by common SSDT generator. Implement
wait_for_aoac_enabled() since required by SoC common code, and ensure
compiled during all stages necessary.
TEST=build/boot google/liara, verify console UART still functional.
