pinctrl: s32cc: initialize gpio_pin_config::list after kmalloc()

Browse Source 
[ Upstream commit 6010d4d8b5 ]

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.
