pinctrl: rockchip: add rk3188 routes to switch between
From: Heiko Stuebner <heiko.stuebner@...> Date: Sat, 10 Nov 2018 20:28:01 +0100
Commit-Message
The rk3188 has pins that are not handled through the regular iomuxing for handling either nand-flash or an emmc and are set through only one specifal setting. So utilize the routing function to simply do that setting depending on one of the core nand/emmc signals that are actually regular pins handled through pinctrl.
