Implement support for HW scheduled scan. The mac80211 code doesn't perform scheduled scans itself, but calls the driver to start and stop scheduled scans. This patch also creates a trace event class to be used by drv_hw_scan and the new drv_sched_scan_start and drv_sched_stop functions, in order to avoid duplicate code.
