ARM: dts: msm: Add GFX CPR device configuration for sdm630

GPU subsystem in sdm630 is supplied by either LDO300(VDD_GFX)
in LDO mode or VDD_CX in BHS mode. This LDO300 is CPR managed
and supports CPR closed-loop operation.  Add CPR device node
with required configuration for supporting CPR closed-loop
operation for sdm630.
