[PATCH v3 0/4] irqchip/meson-gpio: Add support for Meson-S4 SoC

[Qianggui Song]

This patchset add support for GPIO interrupt controller of Meson-S4 SoC
Which has something different with current other meson chips. To
support the new chips, current gpio irqchip driver need to rework as
below:
1. support more than 8 gpio irq lines.
2. add a set trigger type callback function.

With above work, add support for S4 gpio irqchip

Changes since v2 at [1]:
- rework nr channels allocations
- move old controller set_type to a callback

Changes since v1 at [0]:
- fix leaking issue
- fix some typos
- change implementation of new feature.
