Subject: [PATCH 2/3] thermal: core: remove unused functions in power actor section

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.
