NAK. Couple of reasons:

A) Based on AM57xx/DRA7 SoC definitions these pin configuration should
actually be deleted since the pinmuxing is only supposed to be done in
u-boot (thanks to IODelay and other glitch constraints documented in TRM).
B) newer packaging plans do take place that will make reuse of
dra74x.dtsi harder by consolidating the pinmux in a central location.
