soc/intel/alderlake: Remove `soc_gpio_lock_config()` override function
This patch removes `gpios_to_lock` lists and `soc_gpio_lock_config`
override function from Alder Lake SoC as the required config
(SOC_INTEL_COMMON_BLOCK_SMM_LOCK_GPIO_PADS) to perform GPIO PAD lock
configuration using SMM is not enabled.
Note: The current assumption is that the responsibility of locking the
sensitive GPIOs (from getting reprogrammed by OS or other SW) remains
with the mainboard.
BUG=b:208827718
TEST=Able to build and boot brya.
