regulator: add driver for hi6421 voltage regulator
Add driver support for HiSilicon Hi6421 voltage regulators. Two rules for regulator enabling are defined in hi6421 spec: 1) Between disable and enable of each regulator (LDOs or BUCKs), there must be a protection gap. Use @off_on_delay of regulator core to implement this. 2) No two regulators can be enabled at the same time. Use mutex in hi6421_regulator_pdata to ensure this. A protection gap of 100us is added into each LDO/BUCK's .enable_time. Signed-off-by: Guodong Xu <guodong.xu@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

+ This driver provides support for the voltage regulators on the
+ HiSilicon Hi6421 PMU / Codec IC.
+ Hi6421 is a multi-function device which, on regulator part, provides
+ 21 general purpose LDOs, 3 dedicated LDOs, and 5 BUCKs. All
+ of them come with support to either ECO (idle) or sleep mode.
