Subject: [PATCH 2/2] irqchip/meson-gpio: Add support for Meson-G12A SoC

The Meson-G12A SoC uses the same GPIO interrupt controller IP block as the
other Meson SoCs, A totle of 100 pins can be spied on, which is the sum of:

- 223:100 undefined (no interrupt)
- 99:97   3 pins on bank GPIOE
- 96:77   20 pins on bank GPIOX
- 76:61   16 pins on bank GPIOA
- 60:53   8 pins on bank GPIOC
- 52:37   16 pins on bank BOOT
- 36:28   9 pins on bank GPIOH
- 27:12   16 pins on bank GPIOZ
- 11:0    12 pins in the AO domain
