Subject: [PATCH] wifi: ath11k: allow APs combination when dual stations are supported

Since commit f019f4dff2e4 ("wifi: ath11k: support 2 station interfaces"),
if dual stations are supported for a device, we can not configure more that
one AP and/or DFS cannot be enabled.

Enable this by creating a new parameter (ignore_support_dual_stations) to
ignore this feature if it is convenient. Default behavior is to support
dual stations if possible.
