This patchset adds driver for HiSilicon Hi6421v530 PMIC.

Mainline kernel already has driver support to a similar chip, Hi6421.
Hi6421 and Hi6421v530 are both from the same vendor, HiSilicon, but
they are at different revisions. They both use the same Memory-mapped
I/O method to communicate with Main SoC. However, they differ quite a
lot in their regulator designs. Eg. they have completely different LDO
voltage points.

Patch 1 and 2 extends hi6421-pmic-core.c to support Hi6421v530 revision.
Patch 3 add hi6421v530-regulator.c driver for LDO regulators.
Patch 4 fixes an issue for hi6421 regulator, which is not related to v530
         but it's found in this review.
Patch 5 is dts change, it depends and can be applied on hi3660/hikey960
        patchset [1].
Patch 6 enables the relevant config items.

Major changes in v2:
 - instead of writing a new driver, extend hi6421-pmic-core.c
     to support its v530 revision
 - update hi6421v530-regulator.c to use modern regulator driver
     design logics.
