pinctrl: th1520: Update pinmux tables

When Drew took over the pinctrl driver it seems like he didn't use the
git tree I pointed him at and thus missed some important fixes to the
tables describing valid pinmux settings.

The documentation has a nice overview table of these settings but
unfortunately it doesn't fully match the register descriptions, which
seem to be the correct version.
