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.

This allows the core code to change the channel. Code deduplication and
preparation for adding scanning code to the core.

Before preparing the new beacon, check the queue status, flush out all
previous beacons and buffered multicast packets, then (if necessary)
try to recover more gracefully from a stuck beacon condition by making a
less invasive attempt at getting the MAC un-stuck.

When disabling beacons on a vif, intval is 0. Ensure that dev->mt76.beacon_int
is not overwritten in this case, so that beacons continue to work for other
interfaces.

For some reason the BMC queue flush does not work properly if packets were
queued for a BSS0_n interface (secondary vif).
Work around this issue by using the DMA scheduler to filter the queue before
issueing the BMC queue flush.

It is not necessary to time the start of the queue in software, the hardware
already does that for us.
