soc/amd/common/gpio: Add new helper macro PAD_CFG_STRUCT_FLAGS
`flags` field of soc_amd_gpio structure is set only for SCI and SMI configurations. This change adds a new helper macro PAD_CFG_STRUCT_FLAGS that allows setting of all soc_amd_gpio members including `flags` field. This can be used directly by PAD_SCI and PAD_SMI. For all other pad configurations, PAD_CFG_STRUCT macro uses PAD_CFG_STRUCT_FLAGS with flags set to 0. This allows dropping of redundant parameter 0 for flags for all other pad configurations.
