Add a new QCA subcommand QCA_NL80211_VENDOR_SUBCMD_REGULATORY_TPC_INFO
and related attributes qca_wlan_vendor_attr_tpc_links,
qca_wlan_vendor_attr_tpc definition to query transmit power information
on STA interface from the driver for a connected AP.
The information includes regulatory max transmit power limit, AP local
power constraint advertised from AP's Beacon and Probe Response frames.
For PSD power mode, the information includes PSD power levels for each
subchannel of operating bandwidth. The information is driver calculated
power limits based on current regulatory domain, AP local power
constraint and other IEs. The information will be set to target. Target
will decide final TX power based on this and chip specific power
conformance test limits (CTL), and SAR limits.

There is an issue when starting a non-MLD AP on the same interface that
previous operated as an AP MLD. When the previous AP MLD got stopped,
links were not removed when using hostapd. Next non-MLD AP will fail to
start because some nl80211 operations still require link id (e.g., set
freq).
Remove links when AP MLD is stop to avoid such issue. This was already
done in the deinit_ap() handler when using wpa_supplicant, but hostapd
needs to do same.

When processing a (Re)Association Request frame and no corresponding
station is found, try to find the station using the station MLD MAC
address from the Basic ML element, as it is possible that the station
is trying to re-associate but with a different link address (in such
a case the underlying driver would not perform address translations).
When sending the (Re)Association Response frame, use the addresses from
the (Re)Association Request frame and not the AP MLD MAC address, again,
to avoid the address translation done in the driver.

With nl80211 we need to supress the kernel generated event for any
disconnect and deauthenticate. This code is a bit fragile, as it
assumes that an event will happen. Commit b898b65582 ("nl80211: Do
not ignore disconnect event in case of !drv->associated") changed this
to only disconnect when the driver knows it is associated (apparently
required for P2P), however, deauthentication may also occur without
being associated yet.
Looking at the issue, what we are really interested in is whether the
event belongs to a disconnect/deauth command that we have send
ourselves. Any event happening after the disconnect/deauth completes
should not be suppressed (or after the next connect/auth as that would
be sufficient). We therefore need to know from the event stream
whether events were generated before or after disconnect/deauth
command completion.
To do so, send a simple command on the nl_event socket. As this will
be returned back to us in the correct order with regard to the events.
We can therefore use it to safely reset our internal
ignore_next_local_{deauth,disconnect} variables.
