Mark the mt792x USB bus hung on the first control timeout and switch
register access to no-op bus ops. Each failed vendor request may spend
up to MT_VEND_REQ_MAX_RETRY * MT_VEND_REQ_TOUT_MS, about 3 seconds, and
teardown/reset paths can keep issuing such requests after the device has
stopped responding.
Also skip the USB WFSYS reset path after bus_hung is set, since it uses
UHW vendor requests as well.
mt7925u 1-2:1.3: vendor request req:63 off:0018 failed:-110
mt7925u 1-2:1.3: vendor request req:63 off:0018 failed:-110

mt7925u 1-2:1.3: vendor request req:63 off:0018 failed:-110
Avoid repeating those register reads after the bus is known to be hung by
switching register access to no-op handlers.

The USB RX path delivers frames to the stack via mt76_rx_complete() with
a NULL napi pointer, taking the netif_receive_skb_list() path, so it never
benefits from GRO -- unlike the DMA-based mt76 drivers, which pass a real
napi and use napi_gro_receive(). For bulk TCP traffic this is costly, as
every segment traverses the stack individually.
Service the MT_RXQ_MAIN queue from a threaded NAPI, reusing mt76_dev's
existing napi_dev and napi[] rather than adding new fields. The URB
completion handler schedules the napi; its poll drains the URBs, builds
the skbs, resubmits and delivers them through napi_gro_receive(). The MCU
queue stays on the existing RX worker. This enables GRO and moves RX
processing into its own kernel thread, parallelising the datapath.
On mt7921u at HE-MCS 11 (2x2, 80 MHz; fast.com, multiple streams) this
averages ~588 Mbit/s, versus ~424 Mbit/s when the same napi is instead
driven manually from the RX worker, and ~380 Mbit/s for the unmodified
driver.

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.

When queueing packets, only the MT76_RESET flag of the primary PHY
is checked. If the primary PHY is scanning or changing channels, this can
lead to packet loss for tx on the second PHY.
Fix this by passing the phy to the .tx_queue_skb op and using it to check
the correct flag.

Now that AQL works well on all mt76 drivers, completely replace the arbitrary
burst sizing and number of bursts logic for tx scheduling.
For the short period of time in which AQL does not work well yet, limit each
stations to 16 in-flight packets that have no estimated tx time.
This should avoid filling the queue if a station connects and queues up a
large number of packets before rate control information is available, especially
with hardware rate control
