gpio: gpio-hisi: Add HiSilicon GPIO support

This GPIO driver is for HiSilicon's ARM SoC.

HiSilicon's GPIO controller support double-edge interrupt and multi-core
concurrent access.

ACPI table example for this GPIO controller:
Device (GPO0)
{
	Name (_HID, "HISI0184")
	Device (PRTA)
	{
		Name (_ADR, Zero)
		Name (_UID, Zero)
		Name (_DSD, Package (0x01)
		{
			Package (0x02)
			{
				"ngpios",
				0x20
			}
		})
	}
}
