Thanks for this!
I think Olof (and thus, Simon ;)) will be happy if those two patches are
merged.
Other than that, I think we should remove sdhi2_pins_uhs then because it
is the same as sdhi2_pins. And then use later "pinctrl-1 =
<&sdhi2_pins>;". So, basically the same phandles for both pinctrls. We
can re-add the second one when we need it.
