Add hardware parameter support_dual_stations to indicate

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.

Hi Carl,
Unfortunately this commit breaks wifi on a QCM6490 smartphone
(qcm6490-fairphone-fp5) and makes the board crash.
Reverting this commit (plus for conflict resolution 5dc9d1a55e95 ("wifi:
ath11k: add support for QCA2066") and 24395ec11707 ("wifi: ath11k:
provide address list if chip supports 2 stations")) makes wifi work
again.
Thanks for the report. So the broken commit is:
f019f4dff2e4 wifi: ath11k: support 2 station interfaces
This went into v6.9-rc1 so I'm guessing that WCN6750 support will be
fully broken in v6.9? Not good. And most likely Linus will release v6.9
on Sunday so it's too late to get a fix included in the final release.
Carl, can you fix this ASAP? Or should we just revert the broken
commits?
Adding this to our regression tracking:
#regzbot introduced: f019f4dff2e4 ^
#regzbot title: ath11k: WCN6750 firmware crashes during initialisation
Kalle, looks we're not able to fix it before Sunday as I don't have
WCN6750 setup to verify the fix. The fix could be to define a dedicated
function ath11k_init_wmi_config_wcn6750() for WCN6750. I'll send the
patch out so others like Luca can have a try.
