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 are hi6421-pmic cleaning up.
Patch 3 and 4 extends hi6421-pmic-core.c to support Hi6421v530 revision.
Patch 5 add hi6421v530-regulator.c driver for LDO regulators.
Patch 6 fixes an issue for hi6421 regulator, which is not related to v530
but it's found in this review.
Patch 7 is dts change, it depends on and can be applied to hi3660/hikey960
patchset [1].
Patch 8 enables the relevant config items.

Major changes in v4:
- put hi6421-pmic cleanup in separate patches.
- solve review comments from Lee Johes.
- regulator-name should not have '/' character. Otherwise it "Failed to
create debugfs directory"
Major changes in v3:
- in hi6421-pmic-core.c
* use shorter license script.
* arrange #include in alphabetical order.
* using recommended error log messages from Lee Jones.
- in hi6421v530-regulator.c
* remove unused #include files
* arrange remaining ones in alphabetical order.
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.
