Stanislaw GruszkaandFelix Fietkau d4c740f071 mt76x02u: add mt76_release_buffered_frames
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
via MT_TXQ_VO.

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.

Arnd BergmannandFelix Fietkau d1bc504955 mt76: fix building without CONFIG_LEDS_CLASS
When CONFIG_LEDS_CLASS is disabled, or it is a loadable module while
mt76 is built-in, we run into a link error:

drivers/net/wireless/mediatek/mt76/mac80211.o: In function `mt76_register_device':
mac80211.c:(.text+0xb78): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `devm_of_led_classdev_register'

We don't really need a hard dependency here as the driver can presumably
work just fine without LEDs, so this follows the iwlwifi example and
adds a separate Kconfig option for the LED support, this will be available
whenever it will link, and otherwise the respective code gets left out from
the driver object.
