The "uv" key is handled in qcom_smd-regulator.c.. I'm assuming on this
platform, it accepts level idx instead of the regulator properties
and this is intentional?

IPQ9574 RPM accepts regulator properties (uv) and not the level idx.
Hence added the "uv" key in the rpmpd.c

Does it expect the actual voltage? If so, then it is not a power
domain and it should be modelled as a regulator instead.
