soc/amd/common/block/gpio_banks: Rework GPIO pad configuration
Before this patch, gpio_configure_pads_with_override called
program_gpios once for each GPIO that needed to be configured which
resulted in base_num_pads - 1 unneeded master_switch_set/
master_switch_clr sequences for the gpio_configure_pads_with_override
call. Instead implement gpio_configure_pads_with_override as the more
generic function and program_gpios as a special case of that which
passes an empty override configuration and override pad number to
gpio_configure_pads_with_override.
TEST=GPIO configuration and multiplexer register values are the same for
all GPIOs on google/guybrush right before jumping to the payload before
and after the patch.
