You change the pinctl for every .dts so we can drop it from the common
.dtsi completely.

I don't count the .dts which disables the nodes because we enabled it
here. I would setup the mux and stuff here but would not set it to
"okay". It is a bit more straight forward to enable a node rather then:

imx6qdl.dtsi -> disable
common.dtsi -> enable
specific.dts -> disable
