soc/amd/common: move GPIO ACPIMMIO access functions to gpio_banks block
Since the raw GPIO MMIO register access is now only used inside the
gpio_banks block, the gpio_read32 and gpio_write32 functions can be
moved to that block to reduce the visibility and enforce the usage of
the functions provided by the gpio_banks block.
The iomux_read8 and iomux_write8 functions can't be easily moved to the
gpio_banks block, since it's also used in the pre-SOC AMD chipsets that
use the ACPIMMIO access functions directly.
