cpufreq: qcom-hw: Add sysfs file for hw clock domain index

Browse Source 
Default linear mapping no longer works due to non-linear
policy-to-clk_domain index mapping in new chipsets, add
a new sysfs file hw_clk_domain in sysfs directory policy*
so that test script can capture the correct HW clock
domain index.
