Some SR type PLLs need to be configured for a certain rate when
linux boots. Add support for these types of PLLs so that we can
program PLL15's rate on apq8064.

Add support for Qualcomm's PLLs (phase locked loops). This is
sufficient enough to be able to determine the rate the PLL is
running at. We can add rate setting support later when it's
needed.
