soc/amd/common/block/gpio_banks/Kconfig: add option for non-soc/ chips
southbridge/amd/pi/hudson uses the common GPIO bank access code from
soc/amd, but doesn't provide all functionality that would be needed to
use the full functionality. Add a Kconfig option that switches off some
functionality in the common SoC GPIO access code, so that more of the
functionality proviced by the common SoC GPIO code can be used in the
AMD binaryPI chipset and board code.
