In order to consolidate the multiple ways to associate an IRQ chip with
a GPIO chip, move more fields into the new struct gpio_irq_chip.

If there is a need to exclude certain GPIOs from the IRQ domain, you can

+set .irq.need_valid_mask of the gpiochip before gpiochip_add_data() is

are GPIOs in the chip. Drivers can exclude GPIOs by clearing bits from this
mask. The mask must be filled in before gpiochip_irqchip_add() or
gpiochip_irqchip_add_nested() is called.
