msm: thermal: Disable vdd restriction

This does not make sense. Additionaly, start temperature monitoring

msm: thermal: Limit maximum cpu frequency instantly.

If current policy's max cpu frequency is below the maximum
possible frequency, instead of wasting time cycling through
indices, we are now limiting maximum cpu frequency instantly.
However, if limits are changed manually during throttling,
the logic may be confused.

Also, cleanup some kmsg info spam in the process.
