pinctrl: qcom: spmi-gpio: make the irqchip immutable

Browse source 
Commit 6c846d026d ("gpio: Don't fiddle with irqchips marked as
immutable") added a warning to indicate if the gpiolib is altering the
internals of irqchips.

Following this change the following warning is now observed for the SPMI
PMIC pinctrl driver:
gpio gpiochip1: (200f000.spmi:pmic@0:gpio@c000): not an immutable chip, please consider fixing it!

Fix this by making the irqchip in the SPMI PMIC pinctrl driver immutable.
