soc/amd/common/gpio: Add macros for setting fields of soc_amd_gpio

This change adds helper macro PAD_CFG_STRUCT for setting the fields
of `soc_amd_gpio`. Additionally, macros are added for different
operations i.e. pull, output, trigger, int_enable, event_trigger,
wake_enable, debounce, etc. All GPIO configuration macros are updated
to use PAD_CFG_STRUCT instead of setting the fields directly.
