The apq8064 rework to use cacheinfo takes more than expected, so I've
spanwed this series. It is an excerpt of the APQ8064 cpufreq series
[1], so it it continues the version numbering for those patches.

The Subsystem Power Manager (SPM) / SPM AutoVoltageScaling Wrapper2
(SAW2) are hardware blocks used on some of Qualcomm platforms to handle
the voltage rails. It does this by bypassing RPM and directly
interfacing the PMIC. Extend current SPM driver to export this
regulator.
