[PATCH v3 1/3] configs: stm32mp15: enable WDT_ARM_SMC driver

[Yann Gautier]

From: Lionel Debieve <lionel.debieve at foss.st.com>

Enable the arm watchdog over SMC driver. This allows using a secure
watchdog, based on IWDG1 peripheral and managed by OP-TEE.
The driver will be probed if a watchdog node with "arm,smc-wdt"
compatible is enabled.
