regulator: axp20x: fix LDO2/4 description

[ Upstream commit fbb5a79d2fe7b01c6424fbbc04368373b1672d61 ]

Currently we wrongly set the mask of value of LDO2/4 both to the mask of
LDO2, and the LDO4 voltage configuration is left untouched. This leads
to conflict when LDO2/4 are both in use.

Fix this issue by setting different vsel_mask to both regulators.
