I think this is basically OK so,

Just a few small comments/thoughts below...

All those options probably are Tegra20-specific, because the set of
pin-/group-names isn't the same on Tegra20 and Tegra30, so the same
options won't be available. Still, this probably won't actually cause
any name collisions, so it's probably OK to rename these.

Many of these values will be different between Tegra20 and Tegra30.
Hence, the values are all SoC-specific. I suppose you're planning on
having both tegra20.h and tegra30.h define the same set of names, just
with different values? I guess that's fine. It's plausible that
different SoCs might have a different number of instances of some
controllers. I suppose most of these defines should eventually be
replaced by device tree anyway though.
