Qualcomm platforms making use of CPUFreq HW Engine (EPSS/OSM) supply clocks to the CPU cores. But this relationship is not represented in DTS so far. So let's make cpufreq node as the clock provider and CPU nodes as the consumers. The clock index for each CPU node is based on the frequency domain index.
