[1/7] thermal: gov_power_allocator: Rename trip_max_desired_temperature

Commit Message

Lukasz Luba Oct. 25, 2023, 7:22 p.m. UTC

Refactor the code and drop the long name for the trip point. There is
a comment describing the field properly. Use shorten variable name so that
allow to make the code cleaner a bit.

This change is not expected to alter the general functionality.
