The rk3288 pinctrl is very specific to this soc, so should not hog the generic rockchip naming.

Having some sort of ordering proofed helpful in a lot of other places already. So for a larger number of rockchip socs it might be helpful as well instead of an ever increasing unsorted list.

The function is very specific to the rk3288 in its arguments referencing the rk3288 cru and grf and every other rockchip soc has differing cru and grf registers. So make that function naming explicit.
