Add support for PLL found in Qualcomm SDX65 platforms which is used to provide clock to the Cortex A7 CPU via a mux. This PLL can provide high frequency clock to the CPU above 1GHz as compared to the other sources like GPLL0. In this driver, the power domain is attached to the cpudev. This is required for CPUFreq functionality and there seems to be no better place to do other than this driver (no dedicated CPUFreq driver).
