886039036c wcn36xx: Implement firmware assisted scan

f303a93110 wcn36xx: Transition driver to SMD client
The wcn36xx wifi driver follows the life cycle of the WLAN_CTRL SMD
channel, as such it should be a SMD client. This patch makes this
transition, now that we have the necessary frameworks available.

91c3eeba45 wcn36xx: Pad TIM PVM if needed
The wcn36xx FW expects a fixed size TIM PVM in the beacon template. If
supplied with a shorter than expected PVM it will overwrite the IE
following the TIM.

Squashed with fix from Jason Mobarak <jam@cozybit.com>:
Patch "wcn36xx: Pad TIM PVM if needed" has caused a regression in mesh
beaconing.  The field tim_off is always 0 for mesh mode, and thus
pvm_len (referring to the TIM length field) and pad are both incorrectly
calculated.  Thus, msg_body.beacon_length is incorrectly calculated for
mesh mode. Fix this.

57fbcce37b cfg80211: remove enum ieee80211_band
This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of

bands in nl80211 though, so do that and remove the cfg80211 one.

ea1b2b45f5 mac80211: remove short slot/short preamble incapable flags
There are no drivers setting IEEE80211_HW_2GHZ_SHORT_SLOT_INCAPABLE
or IEEE80211_HW_2GHZ_SHORT_PREAMBLE_INCAPABLE, so any code using the
two flags is dead; it's also exceedingly unlikely that any new driver
could ever need to set these flags.

The wcn36xx code is almost certainly broken, but this preserves the
previous behaviour.

there's no need to dance around mutex_unlock, and adds the missing
