msm: acpuclock-8960: Run from PLL8 when reprogramming the HFPLLs

On 8960v2 and 8064 devices, the QSB (Apps Fabric) clock source
may run fast enough such that, if it were used as a CPU clock
source, the CPU may need to run at an elevated voltage to work
reliably.

Instead of incurring the overhead of temporarily increasing the
CPU voltage while reprogramming the HFPLL, use another always-on
source that won't run fast enough to require a CPU voltage
increase.
