 Fix cpufreq HW-ALL coordination handle
Currently cpufreq HW-ALL coordination is handled same way as SW-ALL.
However, SW-ALL will bring more IPIs which is bad for cpuidle.
This patch implement HW-ALL coordination handled in different way from SW-ALL,
for the sake of performance and reduce IPIs. We also suspend/resume HW-ALL dbs 
timer for idle.
