Sure, I can create a "drop unused regulators from 14nm qcm2290 config"
and a second "reuse qcm2290 14nm dsi phy for sm6125" patch, instead of
this one.

In the DT patch you requested me to use CX instead of MX... Which one is
it?
Also note that I moved it from DSI PHY to DSI0 because that's where the
rpmpd opps reside.
