The MT7991A chipset uses PCI device ID 0x7991 (MT7996_DEVICE_ID_2),
but is_mt7996() only checks for 0x7990. This causes MT7991A devices
to use incorrect chip-specific settings, such as:
- MSDU_CNT_V2 instead of MSDU_CNT in TX descriptors
- Wrong WTBL BMC size (32 instead of 64)
- Incorrect prefetch depth for MCU queues

Add hardware airtime fairness (ATF) support, using the MAC's weighted
DWRR scheduler (VoW) to balance TX airtime between stations.
This supplements mac80211's software airtime fairness rather than
replacing it: software ATF keeps scheduling the host TX queues, while
the hardware scheduler enforces fairness on the offloaded path where the
host has no airtime accounting, such as when WED is active. It is enabled
by default on mt7916 and newer chipsets; mt7915 is excluded.
A station's TX airtime weight is taken from mac80211 through the
sta_set_airtime_weight op and applied to the hardware scheduler directly;
the per-AC DWRR quantum levels are derived from it on the fly, mapping
the weight logarithmically onto the global hardware quantum table. ATF
and WATF are enabled by default and can be toggled together at runtime
through the "vow_atf" debugfs file.

mt7925_init_eht_caps() only populates EHT MCS/NSS maps for BW <= 80
and BW = 160, but never sets BW = 320. This means iw phy shows no
320MHz MCS map entries even though the hardware supports 320MHz
operation in the 6GHz band.
Add the missing 320MHz capability bits for 6GHz:
- PHY_CAP0: IEEE80211_EHT_PHY_CAP0_320MHZ_IN_6GHZ
- PHY_CAP1: beamformee SS for 320MHz
- PHY_CAP2: sounding dimensions for 320MHz
- PHY_CAP6: MCS15 support for 320MHz width
- MCS/NSS: populate bw._320 maps for 6GHz band
Introduce is_320mhz_supported() to gate 320MHz on MT7927 only, since
MT7925 does not support 320MHz operation.

Unify all per-chip conditionals under the new is_connac2() helper. This

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.
