msm: cpufreq: Add API to allow limiting of min and max cpu frequencies

CPUFreq provides scaling sysfs nodes to set min and max frequencies, but
there are times when the operating range has to be controlled
irrespective of the scaling limits, to ensure the thermal stability of
the device.

The API allows kernel thermal safeguards to pitch in and limit the
frequencies.
