I believe this initializes every single pingroup on the SoC to
something. In order to prevent any behavior changes, wouldn't it be
better to first fill in this table only with entries that achieve the
same pinmux programming that used to be performed by the C code you're
removing? Then, a separate later patch could fill in missing items in
the pinmux table. I think that'd end up being much safer and easier to
validate.
