platform/x86: intel: int0002_vgpio: Make the irqchip immutable

Commit 6c846d02 ("gpio: Don't fiddle with irqchips marked as
immutable") added a warning to indicate if the gpiolib is altering the
internals of irqchips:

gpio gpiochip4: (INT0002 Virtual GPIO): not an immutable chip, please consider fixing it!

Fix this by making the irqchip in the int0002_vgpio driver immutable.
