Oops, this has a dependency on the patch going through the pinctrl tree,
which causes probelems we like to avoid in the arm-soc tree.

For now, I've changed this to use the GXBB include since the values used
are the same, but we can fix this for good in v4.10-rc, after the GXL
pinctrl changes are merged.
