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.

When a system has said that it has fully specified constraints for its
regulators it is still possible that some supplies may be missing,
especially if regulator support has been added to a driver after the
board was integrated. We can handle such situations more gracefully by
providing a dummy regulator.

Unless the caller has specifically indicated that the system design may
not include a given regulator by using regulator_get_optional() or that
it needs its interactions to have an effect using regulator_get_exclusive()
provide a dummy regulator if we can't locate a real one.

The kconfig option REGULATOR_DUMMY that provided similar behaviour for all
regulators has been removed, systems that need it should flag that they
have full constraints instead.

The driver adds support for the following DA9063 PMIC regulators:
 - 11x LDOs (named LDO1 - LDO11),
 - 6x buck converters (BCORE1, BCORE2, BPRO, BMEM, BIO, BPERI),

Regulators provide following operations:
 - REGULATOR_CHANGE_STATUS and REGULATOR_CHANGE_VOLTAGE for all regulators,
 - REGULATOR_CHANGE_MODE for LDOs and buck converters, where:
     - LDOs allow REGULATOR_MODE_NORMAL and REGULATOR_MODE_STANDBY,
     - buck converters allow REGULATOR_MODE_FAST, REGULATOR_MODE_NORMAL
       and REGULATOR_MODE_STANDBY,
 - REGULATOR_CHANGE_CURRENT for buck converters (current limits).

The driver generates REGULATOR_EVENT_OVER_CURRENT for LDO3, LDO4, LDO7, LDO8
and LDO11.

Internally, PMIC provides two voltage configurations for normal and suspend
system state for each regulator. The driver switches between those on
suspend/wake-up to provide quick and fluent output voltage change.

This driver requires MFD core driver for operation.
