drivers: msm_thermal: use OSM to set CPU freq limits
On SoCs that have OSM hardware, use the hardware to setup the CPU
mitigation limits. Having the OSM control CPU frequencies offloads
mitigation from the CPU, resulting in faster thermal mitigation
response.
The LMH DCVS aggregation does not do a max of the min frequency limits.
Therefore to avoid cpufreq voting any lesser than what KTM decides based
on vdd min restrictions, we update cpufreq as well, only if the min freq
has changed.
