Add support for HiSilicon Hi6421v530 PMIC. Hi6421v530 communicates with
main SoC via memory-mapped I/O.
Hi6421v530 and Hi6421 are PMIC chips from the same vendor, HiSilicon,
but at different revisions. They share the same memory-mapped I/O
design. They differ in integrated devices, such as regulator details,
LDO voltage points.

Use devm_mfd_add_devices() for MFD devices registration and get
rid of .remove callback to remove MFD child-devices. This is done
by managed device framework.

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

of_device_id is always used as const.

The regmap_config struct may be const because it is not modified by the
driver and regmap_init() accepts pointer to const.

This adds driver to support HiSilicon Hi6421 PMIC. Hi6421 includes multi-
functions, such as regulators, codec, ADCs, Coulomb counter, etc.
This driver includes core APIs _only_.
Drivers for individul components, like voltage regulators, are
implemented in corresponding driver directories and files.
Registers in Hi6421 are memory mapped, so using regmap-mmio API.
