I think this patch looks OK. Looking at the kernel pinctrl driver, I
think that before this patch, because some of the mux settings were
deemed invalid by the pinctrl driver, the pinmux settings were not all
applied, and this change fixes it? Ouch! Luckily U-Boot programmed what
is hopefully the same table before the kernel booted!

I think it would be worth mentioning in the commit description where
this data came from.
