The thermal cooling device specified in DT might be instantiated for
a thermal zone trip point with a limited set of OPPs to operate on. This
configuration should be supported by Intelligent Power Allocation (IPA),
since it is a standard for other governors. Change the code and allow IPA
to get power value of lower and upper bound set for a given cooling
device.
