Brian Poole b2a49e88d1 intpm: use MMIO for AMD EFCH CPUs ... Recent AMD CPUs (SMBus PCI revision ID >= 0x51) can disable port-mapped IO and only support memory-mapped IO. In practice this was observed on a Zen 3 CPU where PMIO reads all returned 0xff. Update the driver to use MMIO for these processors while continuing to use PMIO by default.
