Writing directly to Px_DATA_REG modifies pins which are not
indicated by mask, causing gpio_basic_api test to fail.
Use Px_SET_DATA_REG and Px_RESET_DATA_REG to modify only
pins indicated by mask.

Set pin to input with no resistors selected when it is configured as
GPIO_DISCONNECTED.

This adds automatic GPIO latching before going to extended sleep and
restoring state after wakeup.
Mode and state for each pin is stored, then ports are latched to retain
state when PD_COM is disabled during sleep. On wakeup mode and state for
each pin is restored and ports are unlatched to make it work again.

This change allows to have GPIO interrupts configured
that will work while chip enters low power modes where
PD_COM is turned off.
PDC controller can wake up system on GPIO changes even when
PD_COM is off.
This is done by adding PDC entries that will wakeup Cortex-M33
at the same time when WAKEUP controller is programmed to
handle GPIO state changes.

Hardware supports only one edge for GPIO interrupt.
This adds software implementation that hides hardware restriction.
With this change user code can use GPIO_INT_TRIG_BOTH and does not
have to do it in application code.

Init level for GPIO drivers is set PRE_KERNEL_1.
Smartbond(tm) driver had it set to POST_KERNEL by accident.

This adds GPIO driver for Renesas SmartBond(tm) family.
Driver supports pin configuration (input/output) and interrupts on edge.
Interrupts on level are not supported by hardware.
