soc: qcom: cpr: Add support for ACC override parameters
Some SoCs, such as MSM8939, require to use some override parameters for ACC.
This commit use some value from the fuses which indicates whether that
SoC should use the override parameters. The CPR driver updates the pointer
to the ACC descriptor in order to use the override parameters instead.
