CPR (Core Power Reduction) is Qualcomm's implementation of AVS (Adaptive Voltage Scaling).
Dynamic undervolting essentially. It depends on some calibration values encoded
in fuses. This patch dumps the fuse values in the downstream kernel which is useful
to check if the mainline driver is working correctly.
