mfd: hi6421-pmic: Add support for HiSilicon Hi6421v530

Browse Source 
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.
