ARM: tegra: pinmux: partially handle varying register layouts

Browse Source 
Tegra210 moves some bits around in the pinmux registers. Update the code
to handle this.

This doesn't attempt to address the issues with the group-to-group varying
drive group register layout mentioned earlier. This patch handles the
SoC-to-SoC differences in the mux register layout.
