drivers: thermal: msm_thermal: Expose troublesome variables to sysfs to work around around a random reboot

These variables keep messing up and setting themselves to 1944MHz, causing the CPU's max frequency to be set to 1944MHz (causing a reboot as almost no device can handle 1944MHz) after thermald stops throttling and restores the previous frequencies. I will make my Aroma installer write the maxfreq selected to these exposed variables, thus working around the issue.

This is a dirty hack as the max CPU freq now can only be selected via init.d script. I will keep this until I have more time to investigate why the 1944MHz bug occurs.
