Add support for HiSilicon Hi6421v600 SPMI PMIC. Hi6421 includes
multi-functions, such as regulators, RTC, codec, Coulomb counter,
etc.

This driver includes core APIs _only_. You have to select
individual components like voltage regulators under corresponding
menus in order to enable them.
We communicate with the Hi6421v600 via a SPMI bus.
