soc/amd/common/block/acpimmio: add remote GPIO bank access helpers

Currently coreboot for the AMD SOCs only supports accessing the up to 4
main GPIO banks of up to 64 GPIOs each. Some AMD SoCs including Cezanne
have another GPIO bank in the ACPIMMIO region that can contain up to 48
GPIOs beginning with GPIO 256 which is called the remote GPIO bank. The
first 0xc0 bytes of that ACPIMMIO bank are the 32 bit wide GPIO
registers and beginning at offset 0xc0 it has the corresponding 8 bit
wide GPIO MUX registers.
