plat-stm32mp1: fix default setting GPIO as non-secure

plat-stm32mp1: fix default setting GPIO as non-secure

Fixes STM32MP13 sequence that default configures GPIO as non-secure
from set_all_gpios_non_secure() registered at early_init_late initcall
level, that is at same level driver are initially probed by dt_driver
framework. This result on set_all_gpios_non_secure() possibly needing
a bank resource before it is probed. Fix that by removing initcall
function set_all_gpios_non_secure() and default configuring GPIO pins
for STM32MP13 variant on their GPIO bank registering.
