scripts: genpinctrl: genpinctrl.py checks out HAL2 related SoCs

Prevent Git from tracking removal on pinctrl sub-directories for
SoCs relying on HAL2 (currently only the stm32c5 SoC family).
This change prevents genpinctrl.py from removing the pinctrl DTSI
files related to such SoCs while still showing changes if any.
