In order to have the possibility to configure the regulators at system
startup through DM support, all LDOs and bucks must be able to be
changeable. Currently there is a limitation to change the values when
the output is enabled. Since the driver is based on the ROHM BD71837 and a
comment that describes a limitation about switching while the output is
enabled can also be found there, the limitation probably comes from this type.

Add PCA9450 regulator driver. This is complementary driver for the BUCKn
and LDOn regulators provided by the PCA9450 PMIC driver. Currently the
driver permits reading the settngs and configuring the BUCKn and LDOn
regulators.
