Some patches for cleanup...
compile tested only...
Should not break existing user space apps, but they should
get converted asap to use power_swtich_state...

power-trace: Rename power frequency to power_switch_state
this interface/function is not intended for frequency changes
only, but should get used for any P- (processor frequency),
C- (processor sleep), T- (processor throttling), or S- (machine sleep)
state.
Since it's used in cpufreq.c which must be compiled in
and not in acpi-cpufreq.c anymore there is no need to export it
for modules.
