This patch was to add loongson 2k0500, 2k2000 and 3a5000 gpio chip
driver support.
Change in v5:
1. Use boolean initializer for lgpio->chip.can_sleep.
2. Remove the code that about io width gain from ngpios.
3. Fixup the ls7a-gpio and ls2k-gpio items in yaml file.
4. Add the reviewed-by information for dt-bindings patch.
5. Add some comments in loongson_gpio_to_irq.
Change in v4:
1. Reword the title and commit log information.
2. Remove the offset parse in DT and add it in of_device_id and
acpi_device_id's data field.
3. Add more gpio chip dt-bindings support in yaml file.
Change in v3:
1. Reword the dt-bindings patch commit log information.
2. Add "loongson,ls2k1000-gpio" compatible.
Change in v2:
1. Reword the patch commit log information.
2. Add some GPIO register offset description in yaml.
