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.

Removing radio measurements and supported operating class indication
might be needed to reduce binary size for a memory constrained system
that does not need more advanced features. However, removing these is
not recommended since they can help the AP manage the network and STA
steering.

Beacon hinting is a feature that can temporarily change the regulatory

The wpa_auth_callbacks for mesh was missing a for_each_sta
implementation. This is an issue with pmksa cache, as when a cache entry
expires the for_each_sta callback is called in order to clear the pmksa
reference for all sta that was using this entry. Not having a
for_each_sta callback will prevent this cleanup to happen then a sta
could still use this pmksa entry even after it has been freed.
This used after free was not a problem up until recently where
dpp_pkhash is now stored in pmksa entry and retreived later on causing
crash with below backtrace:

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.

When connecting, pending_bssid is set to the main link that we are
authenticating/associating on. Later on, the MLD MAC address will be
stored in the bssid, but we may also try to deauthenticate before we are
connected and in that case, pending_bssid is not yet set to the MLD MAC
address.
As such, use the ap_mld_addr instead of pending_bssid if n_mld_links is
non-zero. This is the sensible thing to do and expected behavior on
nl80211.

For AP MLD, when BSSID configuration is specified without mld_addr, the
