romed8hm3: Add phosphor-regulators config
The default configuration of the VRM that supplies the VDDCR_CPU supply
rail (ISL96147) provides a voltage that's significantly too high; we
need to twiddle some magic bits in a specific register to bring it into
spec (no public documentation of this particular VRM is available as far
as I've been able to find, unfortunately).
