regulator: stpmic1: Add static const qualifier at peroper places
The regulator_linear_range arrays and stpmic1_regulator_cfgs are only accessed by this driver and the values are never changed so make them static const. regulator_ops variables can also be const. Also clean up a few empty lines in regulator_linear_range array. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>
