LM363X regulator driver supports LM3631 and LM3632.
LM3631 has 5 regulators. LM3632 provides 3 regulators.
One boost output and LDOs are used for the display module.
Boost voltage is configurable but always on.
Supported operations for LDOs are enabled/disabled and voltage change.

Two LDOs of LM3632 can be controlled by external pins.
Those are configured through the DT properties.

The driver depends on MFD_STW481X but there isn't a build dependency so
it's a good idea to allow the driver to always be built when the
COMPILE_TEST option is enabled.

That way, the driver can be built with a config generated by make
allyesconfig and check if a patch would break the build.

Add driver support for HiSilicon Hi6421 voltage regulators.

Two rules for regulator enabling are defined in hi6421 spec:
1) Between disable and enable of each regulator (LDOs or BUCKs), there must
   be a protection gap. Use @off_on_delay of regulator core to implement this.
2) No two regulators can be enabled at the same time. Use mutex in
   hi6421_regulator_pdata to ensure this. A protection gap of 100us is added
   into each LDO/BUCK's .enable_time.
