cpufreq: changes to adapt for opensource clock framework
Update cpufreq driver to adapt to opensource clock framework
Opensource clock framework dev_clk_get returns with the
different clock handle for all cpu cores with same clock source
This is different in the existing clock framework where
dev_clk_get returns with the same clock handle for the cores
which shares the same clock source.
Cpufreq driver was compatible with the existing clock
framework but with the opensource clock framework we need
to handle the different clock handles for all the cores
even the clock source is common.
