Log Message:
Use MMIO for PM register access on newer revision's devices.

 Newer revision's device only support memory mapped access. At least,
X670E's SMBus device that the revision ID is 0x71 doesn't support I/O
access. Use MMIO access for newer devices. Linux uses >= 0x51 for the
check, so we do the same check. Note that X570's SMBus(rev. 0x61) supports
I/O access...
