ARM: dts: msm: Add APC voltage regulator for mdmfermium 



Move to SPM controlled regulator for APC rail. Add CPR
regulator needed for APC voltage rail on mdmfermium.

Add CPR fuse parameters for target quotient, ring oscillator
selector and initial voltage for the corners as per the fuse
definitions for mdmfermium.

Do not enable the closed-loop CPR configuration.
