Felix Fietkau 33f29d2345 wifi: mt76: relicense to BSD-3-Clause-Clear
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.

The HW can apply header translation to first fragmented frame, and

Felix Fietkau fa14e7f331 mt76: mt7615: rework rx phy index handling
Overwriting the RMAC_CHFREQ register is not reliable enough, as the firmware
could potentially write it again.
Since there is no PHY index indication in the rx info, we need to use another
way:

If both PHYs are using different channels, find the PHY where chfreq matches
the register value.

The only corner case remaining is when both PHYs are using the same channel.
In that case, the per-packet noise value on the primary PHY will have
information belonging to the chains of the secondary PHY from the previous
received packet of that PHY. The secondary PHY will set noise to 0 for extra
chains.

MT7622 does not have the CR4 microcontroller sitting in the data path.
Because of that, it uses the chip's native tx descriptor format instead of
something parsed and converted by the firmware.
