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.
