pinctrl: exynos: Use one IRQ domain per pin bank
Instead of registering one IRQ domain for all pin banks of a pin
controller, this patch implements registration of per-bank domains.
At a cost of a little memory overhead (~2.5KiB for all GPIO interrupts
of Exynos4x12) it simplifies driver code and device tree sources,
because GPIO interrupts can be now specified per banks.
Example:
device {
/* ... */
interrupt-parent = <&gpa1>;
interrupts = <3 0>;
/* ... */
};
