pinctrl: s32cc: initialize gpio_pin_config::list after kmalloc()
[ Upstream commit 6010d4d8b55b5d3ae1efb5502c54312e15c14f21 ]
s32_pmx_gpio_request_enable() does not initialize the newly-allocated
gpio_pin_config::list before adding it to s32_pinctrl::gpio_configs.
This could result in a linked list corruption.
Initialize the new list_head with INIT_LIST_HEAD() to fix this.
Fixes: fd84aaa8173d ("pinctrl: add NXP S32 SoC family support")
