Stanislaw GruszkaandFelix Fietkau e9c017190e mt76usb: use usb_dev private data
Setup usb device private data. This allows to remove mt76u_buf->dev
and simplify some routines as no longer we need to get usb device
through usb interface.

Create software MT_TXQ_PSD queue for USB and map it to MT_TXQ_VO
since we do not have USB endpoint for PSD. This should make
mt76_release_buffered_frames() work by sending released frames

Stanislaw GruszkaandFelix Fietkau abcb544579 mt76x02: do not enable RTS/CTS by default
My commit 26a7b5473191 ("mt76x02: set protection according to ht
operation element") enabled by default RTS/CTS protection for OFDM
and CCK traffic, because MT_TX_RTS_CFG_THRESH is configured to non
0xffff by initvals and .set_rts_threshold callback is not called by
mac80211 on initialization, only on user request or during
ieee80211_reconfig() (suspend/resuem or restart_hw).

Enabling RTS/CTS cause some problems when sending probe request
frames by hcxdumptool penetration tool, but I expect it can cause
other issues on different scenarios.

Restore previous setting of RTS/CTS being disabled by default for
OFDM/CCK by changing MT_TX_RTS_CFG_THRESH initvals to 0xffff.

is done after we get back to operating channel, so we do not perform
queue cal work. Fix this queue cal work from sw_scan_complete().

On mt76x0 we have to restore gain in MT_BBP(AGC, 8) register after
scanning, as it was multiple times modified by channel switch code.
So queue cal work without any delay to set AGC gain value.

Similar like in mt76x2 init AGC gain only when set operating channel
and just check before queuing cal work in sw_scan_complete() if
initialization was already done.
