[PATCH] pinctrl: rockchip: Add iomux-route switching support for rk3288

[Heiko Stuebner]

So far only the hdmi cec supports using one of two different pins
as source, so add the route switching for it.

If I didn't mess up any numbering, the pinctrl change should look like
the following patch.

Hope that helps
