Oh we already have that I think, Mika Westerberg and Andy Shevcheno
implemented that for anyone using CONFIG_GPIOLIB_IRQCHIP, and
this driver does. Timur please check: irq_need_valid_mask, irq_valid_mask
usage.

These patches already use irq_valid_mask!  But that doesn't block complete
access to the GPIO.

Aha sorry for my ignorance :(

Doesn't that mean we need something like irq_valid_mask but rather
gpio_valid_mask that just block all usage of certain GPIOs?
