With chanctx drivers using hardware scan or remain-on-channel,
mac80211 does not know when the radio goes off-channel, which breaks
its software beacon loss detection.
Implement per-link beacon monitoring in the driver. Track the last
beacon timestamp per link and check for beacon loss periodically from
the mac_work handler.
Beacon monitoring is initialized on association and on late link
activation, and cleared on disassociation. The beacon_mon_last
timestamp is reset when returning from offchannel and after channel
switches to prevent false beacon loss detection.

Since mt76 uses chanctx, mac80211 does not send nullfunc power save
notifications when the driver goes offchannel for scan or ROC.
Add mt76_offchannel_notify() to send nullfunc PM=1 before going
offchannel and PM=0 after returning, so that the AP can buffer
frames during the absence.
For MLO, iterate all vif links on the phy and set
IEEE80211_TX_CTRL_MLO_LINK so that the driver's tx_prepare_skb
resolves the correct per-link wcid.

mt76_remain_on_channel() always creates an HT20 chandef and goes
offchannel, even when the ROC channel matches the operating channel.
This unnecessarily narrows bandwidth and triggers beacon stop/restart.
When the ROC channel matches the current operating channel, preserve
the full chandef and skip the offchannel transition, matching the
optimization already present in the scan code.
Extract the shared same-channel detection into mt76_offchannel_chandef()
and use it in both ROC and scan paths.

On channels with NO_IR or RADAR flags, wait for beacon before sending
probe requests. Allows active scanning and WPS on restricted channels
if another AP is already present.

ieee80211_tx_prepare_skb() has three error paths, but only two of them
free the skb. The first error path (ieee80211_tx_prepare() returning
TX_DROP) does not free it, while invoke_tx_handlers() failure and the
fragmentation check both do.
Add kfree_skb() to the first error path so all three are consistent,
and remove the now-redundant frees in callers (ath9k, mt76,
mac80211_hwsim) to avoid double-free.
Document the skb ownership guarantee in the function's kdoc.

MediaTek has asked to switch from the ISC license to BSD-3-Clause-Clear,
in order to improve clarity and the legal integrity of the code.
The BSD-3-Clause license includes the "no endorsement" clause, which is
important for protecting the reputation of the original authors and
contributors by preventing unauthorized use of their names for endorsement
purposes.
This clause is absent in the BSD-2-Clause license, which is more permissive
but lacks this specific protection.
This change also cleans up the license of some Kconfig/Makefile files,
which were accidentally marked as GPL.
The GPL 2.0 remains in use on mt76x0, as well as two source files in mt7615
for which the license situation still needs to be clarified.
