i2c: piix4: Add EFCH MMIO support to region request and release
EFCH cd6h/cd7h port I/O may no longer be available on later AMD
processors and it is recommended to use MMIO instead. Update the
request and release functions to support MMIO.
MMIO request/release and mmapping require details during cleanup.
Add a MMIO configuration structure containing resource and vaddress
details for mapping the region, accessing the region, and releasing
the region.
