Ryder LeeandFelix Fietkau 7714dc914d mt76: report Rx timestamp
Frame reception timestamp (low 32-bits) that indicates the value of the
local TSF timer value at the time the first bit of the MAC header in the
received frame (PPDU unit) arriving at the MAC.

Felix Fietkau b860906689 mt76: mt7615: fix chip reset on MT7622 and MT7663e
After chip reset, the DMA scheduler needs to be initialized as well.
Since the code is PCI/SoC specific, move it to pci_mac.c, so that it
can depend on a function in dma.c

Felix Fietkau e861cb0518 mt76: rely on AQL for burst size limits on tx queueing
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

Felix Fietkau 25dd8bdae3 mt76: mt7615: 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.
