mfd: Add HI6421 PMIC Core driver
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.
