please don't amend that function list anymore.

Only RK_FUNC_GPIO serves a real purpose but having constants FUNC_7 mapping 
simply to 7 does not help understand things better, so it's way easier to just 
have "7" as function in pinctrl entries in the devicetree.

That list is mainly a remnant to keep compatibility with old devicetrees and I 
guess I should add a deprecated notice at some point :-) .
