Subject: [PATCH 07/11] gpio/rockchip: rk_gpio support v2 gpio controller
The v2 gpio controller add write enable bit for some register,
such as data register, data direction register and so on.
This patch support v2 gpio controller by redefine the read and
write operation functions.
Also adds support for the rk3568 pinctrl device.
Squash all fixes into this commit.
