drivers: thermal: cpu_cooling: Use platform ops callback for min state 



CPU cooling device notifies the cpufreq driver if it has a new min
frequency floor request. CPU cooling device right now ignores the
platform specific callback to set the min state.

Use the platform specific min frequency callback to place the min
frequency request.
