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.
