Lorenzo BianconiandFelix Fietkau 11602b8505 mt76: mt7615e: process txfree and txstatus without allocating skbs
Similar to mt7915 driver, process txfree and txstatus without allocating
skbs in order to reduce pressure on the memory allocator

Felix Fietkau 23ecadd4af mt76: mt7615: fix hardware error recovery for mt7663
MT7663 uses different bits for communicating reset commands/status between MCU
and host. Also add an extra initial reset command.

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.
