Felix Fietkau 5e0c587b9a mt76: mt7915: clean up station stats polling and rate control update
Queueing a per-sta work item from the tx free path can become very expensive
under load. This work is only supposed to pull rate control stats every
second and deal with rate control changes.

Additionally, the rate control update code was wrong, because it was
confusing bit masks and bit numbers in test_bit.

Fix this by introducing a dedicated device work item for rate control
updates, and by polling station stats from the phy mac work.
Stations requiring polling or rate control updates are added to lists
protected by dev->sta_poll_lock.

Shayne ChenandFelix Fietkau c6ea163c01 mt76: mt7915: directly read per-rate tx power from registers
Since driver no longer handler per-rate tx power setting, we need to
read the power values directly from registers.

Shayne ChenandFelix Fietkau b3a4d78914 mt76: mt7915: rework the flow of txpower setting
Clean up the flow of per-rate txpower limit setting to get rid of
dulplicate work since it has already been handled by firmware, and set
proper max_power based on different channels and regdomains.

Ryder LeeandFelix Fietkau dacc2d2967 mt76: mt7915: add MU-MIMO support
Enable MU-MIMO DL/UL and add relative counters in debugfs.

Currently MU modules read WTBL first to notify BA changes to
other cross modules, so adjust mt7915_mcu_sta_ba() accordingly.

Ryder LeeandFelix Fietkau a5368e5cad mt76: mt7915: set peer Tx fixed rate through debugfs
Driver can manually set fixed rate for each peer through debugfs.

May use .set_bitrate_mask callback and iterate stations under the
current vif to achieve the aim once it supports HE rate.

Ryder LeeandFelix Fietkau 158253e2c1 mt76: mt7915: add .sta_add_debugfs support
This generation supports much more per-peer statistics than legacy ones,
so add .sta_add_debugfs accordingly.

This is convenient to set/get more settings/counters in the long run.
