cpufreq:LAB: Change method of boost state preserving
It is not necessary to change the boost state when LAB governor is entered,
since LAB will change it according to its own politics. Only enter state
is preserved.
When leaving the LAB, only when required, work is scheduled to restore boost
initial state.
