Do not register the RTC interrupt when it's not used by OP-TEE as it
prevents non-secure world from handling that interrupt.

The RTC interrupt line is only used if the RTC is set as a wakeup source
or RTC is secured by the RIF (only for STM32MP2x) and RTC PTA and
async notif are enabled.

drivers: stm32_gpio: move dt_flags support in the new ops configure

Move the GPIO configuration based on dt_flags previously done in

To avoid glitch on GPIO line, the write in register GPIO_MODER is only
kept in the ops stm32_gpio_set_direction(), called by gpio framework
function gpio_configure() after the call of configure ops, so
we have no more transient GPIO input configuration.

Moreover, this patch allows to correctly apply the dt_flags when
they are modify after the call of stm32_gpio_get_dt(),
for example in drivers regulator fixed and gpio.

drivers: gpio: add configure functions

Align the OP-TEE GPIO driver with GPIO lib (devm_gpiod_get_index with
enum gpiod_flags) and add a way to select the GPIO configuration directly
during request with the new function, gpio_dt_cfg_by_index().

This patch remove assumption on GPIO direction (gpio input was assumed in
GPIO driver) or output level when the GPIO is requested by consumer.
with this patch it must be requested explicitly with:
- GPIO_IN: configure the input GPIO
- GPIO_ASIS: direction is managed by caller later with gpio_set_value()
call.
- GPIO_OUT_LOW / GPIO_OUT_HIGH: output GPIO at expected level,
the sequence for GPIO have the correct order to avoid glitch by using
the gpio function at the correct order.

This patch is a preliminary step for the introduction of ops configure.
The API gpio_dt_get_by_index() is keep for backward compatibility but
should be used with gpio_configure() or replaced by gpio_dt_cfg_by_index().

Now gpio_configure() is only used in the 2 drivers, regulator_fixed and
regulator_gpio, because in these drivers the flags gpio->dt_flags are
modified after call of gpio_dt_get_by_index().

For get_voltage_level_gpio(), GPIO_OUT_HIGH is used by default as it is
done in Linux function of_get_gpio_regulator_config().

Implement .stop watchdog handler in order to allow the platform to

The platform does not allow a way to stop an IWDG once started but a
solution exists.
We disable the platform reset ability of the IWDG we use and the IRQ
associated if the reset property is present in the DT.

Be careful, on STM32MP2 platforms, in A35TDCID, the system reset of the
IWDG1 cannot be disabled. Therefore, only the IWDG2 can be stopped.
The same behavior applies for IWDG3 in M33TDCID, you'll have to use the
IWDG4.
