David Spinadel 633e271326 mac80211: split sched scan IEs
Split sched scan IEs to band specific and not band specific
blocks. Common IEs blocks may be sent to the FW once per command,
instead of per band.

This allows optimization of size of the command, which may be
required by some drivers (eg. iwlmvm with newer firmware version).

As this changes the mac80211 API, update all drivers to use the
new version correctly, even if they don't (yet) make use of the
split data.
