A platform_driver does not need to set an owner, it will be populated by the
driver core.

The valid_modes_mask and *dev are not used in this driver, remove them.
Current code uses devm_regulator_register, so we don't need *regulator in
hi6421_regulator_info. Use a local variable instead.
Also removes a few unnecessary inclusion of header files.

style fix for warnings. 'else' with a single 'return' is usually not
required.

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.
