Subject: [PATCH] rtw88: set WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL, mac80211 supports it

Set wiphy flag WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL, because mac80211
actually supports it. With the flag set, driver can accept ROC
event from wpa_supplicant or some other user space tools.

Do note that driver is most used to run a station mode vif and is
using sw_scan instead of use_chan_ctx. So, if the driver is going
to use chan_ctx or hw_scan, must make sure that ROC can work.
