While the kernel is booting up, APSS PLL will be running at 800MHz with
GPLL0 as source. Once the cpufreq driver is available, APSS PLL will be
configured to the rate based on the opp table and the source also will be
changed to APSS_PLL_EARLY.

Also, dynamic scaling of CPUFreq is not supported on IPQ5332, so to switch
between the frequencies we need to park the APSS PLL in safe source,
here it is GPLL0 and then shutdown and bring up the APSS PLL in the
desired rate. So this patch is preparatory one to enable the CPUFreq on
IPQ5332.
