Fixed regulators currently always end up in the return -EINVAL else
branch. In Linux, the fixed regulator driver parses the DT and will
populate fixed_uV if min_uv and max_uv are equal. For barebox, it's
easier to do this in the core, but the result is the same:
We now can call regulator_get_voltage for fixed regulators.
