soc/intel/common/gpio: Rework PAD config macro to add lock support

This patch extends `struct pad_config` to add new variable for gpio
lock action.

Additionally, it creates new GPIO PAD configuration macros that perform
GPIO pad configuration and pad lock configuration as well.

List of new macros are:
1. PAD_CFG_NF_LOCK
2. PAD_CFG_GPO_LOCK
3. PAD_CFG_GPI_LOCK
4. PAD_CFG_GPI_TRIG_OWN_LOCK
5. PAD_CFG_GPI_GPIO_DRIVER_LOCK
6. PAD_CFG_GPI_INT_LOCK
7. PAD_CFG_GPI_APIC_LOCK
8. PAD_CFG_GPI_IRQ_WAKE_LOCK

Mainboard users can use the above macros to lock the PAD after
configuration.

So far on IA chipset, the default GPIO pad lock configuration reset
type is POWERGOOD hence, it's recommended as per GPIO BWG (doc: 630603)
to configure the GPP PAD reset type the same as lock configuration
reset type to avoid GPP reset value misconfiguration issue.
