Add the QCOM RPMh regulator driver to manage PMIC regulators
which are controlled via RPMh on some Qualcomm Technologies, Inc.
SoCs.  RPMh is a hardware block which contains several
accelerators which are used to manage various hardware resources
that are shared between the processors of the SoC.  The final
hardware state of a regulator is determined within RPMh by
performing max aggregation of the requests made by all of the
processors.

Add support for PMIC regulator control via the voltage regulator
manager (VRM) and oscillator buffer (XOB) RPMh accelerators.
VRM supports manipulation of enable state, voltage, and mode.
XOB supports manipulation of enable state.

Assuming Mark is OK with this, it looks good to me now.  My previous
feedback is resolved and I'm OK with the hardcoded current loads in
the driver for now until we come up with something better.

NOTE: Presumably this can't actually land anywhere :( until the RPMh
patchset lands somewhere and that's still sitting in limbo waiting for
Qualcomm to spin the patches.  Presumably once RPMh lands someone will
need to put it somewhere that can be pulled into the relevant trees so
we don't need to wait for a whole merge window...
