[PATCH v2] ath10k: enable VHT for IBSS

[Janusz Dziedzic]

Enable VHT support for IBSS, while mac80211/cfg80211 and
wpa_supplicant already support this.

In my test env, ath10k 2x2 I get:
(udp) ath10k-1 >>>> ath10k-2 (server) -  speed: 419 Mbits/sec
(tcp) ath10k-1 >>>> ath10k-2 (server) -  speed: 404 Mbits/sec

During tests I used wpa_supplicant (current version), which
already support IBSS VHT, and choose highest available BW.
