wifi: ath11k: support 2 station interfaces

Browse source 
Add hardware parameter support_dual_stations to indicate whether 2 station
interfaces are supported. For chips which support this feature, limit total
number of AP interface and mesh point to 1. The max interfaces are 3 for such
chips.

The chips affected are:

 QCA6390 hw2.0
 WCN6855 hw2.0
 WCN6855 hw2.1

Other chips are not affected.

For affected chips, remove radar_detect_widths because now
num_different_channels is set to 2. radar_detect_widths can be set only when
num_different_channels is 1, see mac80211 function wiphy_verify_combinations
for details. This means that in affectected chips DFS cannot be enabled in AP
mode.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3
