Subject: [PATCH v7 4/4] cpufreq: ondemand: use all CPUs in update_sampling_rate

Modify update_sampling_rate() to check, and eventually immediately
schedule, all CPU's do_dbs_timer delayed work.

This is required in case of software coordinated CPUs, as we now have a
separate delayed work for each CPU.
