soc/amd/common/include/acpimmio: drop 16 and 32 bit PM2 access functions
The PM2 ACPIMMIO region should only be accessed with 8 bit accesses.
Using 16 or 32 bit read accesses will return the data from the first
byte for all 2 or 4 bytes and 16 or 32 bit write accesses will result in
only the first byte being written which is both unexpected behavior.
