thermal: core: Remove unused functions in power actor section

Browse source 
Since the Intelligent Power Allocation (IPA) uses different way to get
minimum and maximum power for a given cooling device, the helper functions
are not needed. There is no other code which uses them, so remove the
helper functions.
