i2c: piix4: Add EFCH MMIO support to SMBus base address detect
The EFCH SMBus controller's base address is determined using details in FCH::PM::DECODEEN[smbusasfiobase] and FCH::PM::DECODEEN[smbusasfioen].These register fields were accessed using cd6h/cd7h port I/O. cd6h/cd7h port I/O is no longer available in later AMD processors. Change base address detection to use MMIO instead of port I/O cd6h/cd7h.
