cfg80211/nl80211: add support for scheduled scans
Implement new functionality for scheduled scan offload. With this feature we
can scan automatically at certain intervals.
The idea is that the hardware can perform scan automatically and filter on
desired results without waking up the host unnecessarily.
Add NL80211_CMD_START_SCHED_SCAN and NL80211_CMD_STOP_SCHED_SCAN
commands to the nl80211 interface. When results are available they are
reported by NL80211_CMD_SCHED_SCAN_RESULTS events. The userspace is
informed when the scheduled scan has stopped with a
NL80211_CMD_SCHED_SCAN_STOPPED event, which can be triggered either by
the driver or by a call to NL80211_CMD_STOP_SCHED_SCAN.
