		2. Add the reviewed-by information.
Change in v3:
		1. Separate some changes of MAINTAINERS file and enter the first patch.
Change in v2:
		1. Drop "loongson,gpio_base" and "gpio-ranges" will cover it.
		1. Drop "loongson,conf_offset", "loongson,out_offset", "loongson,in_offset",
		   "loongson,support_irq" and kernel driver will initial them that depend
		   compatible in kernel.
		3. Fixup maintainer for this driver.
