When the user is reading cur_state from the thermal cooling device for
Intel powerclamp device:
- It returns the idle ratio from Package C-state counters when
there is active idle injection session.
- -1, when there is no active idle injection session.
This information is not very useful as the package C-state counters vary
a lot from read to read. Instead just return the last requested cur_state.
