pinctrl: rockchip: fix RK3308 pinmux bits

[ Upstream commit 1f3e25a068832f8892a5ff71467622d012f5bc9f ]

Some of the pinmuxing bits described in rk3308_mux_recalced_data are wrong,
pointing to non-existing registers.

Fix the entire table.

Also add a comment in front of each entry with the same string that appears
in the datasheet to make the table easier to compare with the docs.

This fix has been tested on real hardware for the gpio3b3_sel entry.
