regulator: tps6105x: Convert to use regmap helper functions
Since commit 7e5071199355 ("mfd: tps6105x: Use i2c regmap to access registers"), we can use regmap helper functions instead of open coded. Signed-off-by: Axel Lin <axel.lin@ingics.com> Tested-by: Denis Grigoryev <grigoryev@fastwel.ru> Signed-off-by: Mark Brown <broonie@kernel.org>
