Support voltage control for regulators on ROHM BD71815 PMIC.

ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED).
Bucks 1 and 2 support HW state based voltage level and enable states. Other
regulators support HW state based enable states. All bucks and LDOs 1-5
allow voltage changes for RUN state and LDO4 can be enabled/disabled via
GPIO.

LDO3 does support changing between two predetermined voltages by using
a GPIO but this functionality is not included in this commit.

All errors (new ones prefixed by >>):

   qcom-rpmh-regulator.c:(.text+0x2fc): undefined reference to `rpmh_write_async'

Which is due to REGULATOR_QCOM_RPMH depending on
QCOM_RPMH || COMPILE_TEST. The problem is that QOM_RPMH can now
be a module, which in that case requires REGULATOR_QCOM_RPMH=m
to build.

However, if COMPILE_TEST is enabled, REGULATOR_QCOM_RPMH can be
set to =y while QCOM_RPMH=m which will cause build failures.

The fix here is to add (QCOM_RPMH=n && COMPILE_TEST) to the
dependency.

Feedback would be appreciated!
