Felix Fietkau f701fad5c0 wifi: mt76: mt7925: fix infinite loop in UNI event TLV parsing
The event TLV loops accept a zero-length TLV, which advances neither the
cursor nor the remaining length, so a malformed event hangs the caller.
mt7925_mcu_uni_roc_event() additionally walked past the end of the skb,
since it never checked the declared length against the remainder.

Replace the five open-coded loops with a shared iterator that rejects
lengths below the TLV header and beyond the remaining buffer, and check
the per-tag payload sizes before dereferencing them.

While here, make the RSSI monitor event read from the current TLV rather
than from the start of the list.

Sean WangandFelix Fietkau 833ad5705d wifi: mt76: mt7925: support new WoW pattern TLV
Newer mt7925 firmware uses a shorter WoW pattern TLV with rsv[3]. Select
the v2 layout based on the firmware build date, while keeping the old
layout for older firmware.

This also makes the WoW pattern handling compatible with newer devices
such as MT7928.

Sean WangandFelix Fietkau f716cf9b6e wifi: mt76: mt7925: pass WCID indices to bss_basic_tlv()
Drop the mt792x_sta_to_link() lookup in mt7925_mcu_bss_basic_tlv() and
pass the resolved WCID indices from the caller instead. The link
context is already known, so the lookup is redundant.

This makes link ownership explicit and keeps the helper lookup-free.

No functional change intended.

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.

Filogic 360, which can support Station, AP, P2P, and monitor modes.
Filogic 360 supports max 4096-QAM/160MHz radio operation at 6 GHz, 5 GHz,
or 2.4 GHz with 2x2 antennas. This chip supports PCIe and USB bus type.

mt7925 supports Wi-Fi 6E and EHT rate with single link only at this moment,
whereas Wi-Fi 7 and its specific features are working in progress. They will be
introduced in further patches.

The driver is build tested by Intel's kernel test robot with both GCC and Clang
with several architecture. Sparse reports no warnings.

There are multiple authors, they are listed in alphabetical order below.
