Felix Fietkau 72f0979566 mt76: mt7915: add support for accessing mapped registers via bus ops
Makes it possible to read/write them via debugfs, similar to mt7615/7603

Felix Fietkau 2f1318a06d mt76: convert from tx tasklet to tx worker thread
This should improve performance by allowing the scheduler to move the tx
scheduling work to idle CPUs

Felix Fietkau 5cf34cda70 mt76: mt7915: significantly reduce interrupt load
On 7615 and newer, DMA completion only triggers unmap, but not free of queued
skbs, since pointers to packets are queued internally.
Because of that, there is no need to process the main data queue immediately
on DMA completion.
To improve performance, mask out the DMA data queue completion interrupt and
process the queue only when we receive a txfree event.
This brings the number of interrupts under load down to a small fraction.

Felix Fietkau 23dbd64d63 mt76: mt7915: schedule tx tasklet in mt7915_mac_tx_free
The previous scheduling round may have been limited by AQL.
More frames might be available after the tx free run.

Felix Fietkau 3743e7c904 mt76: mt7915: optimize mt7915_mac_sta_poll
Since DMA completion does not imply tx completion, it makes more sense to
poll for airtime from mt7915_mac_tx_free.
Reduce the runtime of the function by moving all items from dev->sta_poll_list
to a local list once and process any stations that were added afterwards
on the next run

Felix Fietkau 1eb94624bb mt76: mt7915: do not do any work in napi poll after calling napi_complete_done()
Fixes a race condition where multiple tx cleanup or sta poll tasks could run
in parallel.

Overwrite hw queue id for non-bufferable management frames if the hw/fw
support always txq (altxq) in order to be in sync with mac txwi code

Ryder LeeandFelix Fietkau c6b002bcdf mt76: add mac80211 driver for MT7915 PCIe-based chipsets
Add support for the MediaTek latest generation IEEE 802.11ax 4x4
device MT7915E, which supports concurrent dual-band operation at
both 5GHz and 2.4GHz.

Note that this patch just add basic part and will add more HE
capabilities support in the further patches.

The driver supports AP, Station, Mesh and monitor mode.
