What's the logic behind the "ldo4_sm2" v.s. "sm2" naming? Does it match
the data sheet in some way? If not, it might be better to name this
something like "tps6586x_ldo4_voltages" and "tps65863_ldo4_voltages".

Why rename the macro?
There's an embedded TAB before "nbits".

Rather than changing all the macros and table entries, wouldn't it be
much simpler to:
1) Make tps6586x_regulator[] only contain all the common regulator
definitions.
2) Add new version-specific tables for each version of regulator, so
tps6586x_other_regulator[] and tps65863_regulator[].
3) Have probe() walk multiple tables of regulators, selecting which
tables to walk based on version.
That would result in a much smaller and less invasive diff.
