wifi: mac80211: AP: handle DBE for clients
In AP mode, track the BSS non-DBE bandwidth and apply
that to all non-DBE clients, then track OMP updates
from the clients and enable/disable DBE accordingly.
For now don't send a response, clients need to have a
timer anyway (it's up to the driver to set the right
timeout in UHR capabilities.)
