Unlike on earlier chips, DMA completion on MT7615 does not imply actually
having sent out any packets.
Since AQL will prevent filling the hardware queues and will only allow more
packets to be passed to the driver after tx completion, it makes much more
sense to schedule the tx tasklet there.
This is also needed for scheduling tx in testmode support

In MT7915, hardware queue map is flexible. However, certain firmware modules

While looking at the ETSI regulatory domain definitions
and a patch, which allows more channels for ath10k, I also
checked the channels allowed for mt76.
ETSI regulations would possibly allow to add channels 32, 68,
96, 144, 169 and 173. IEEE 802.11-2016 defines no operating class
for channels 32, 68 and 96. This leaves us channels 144, 169 and 173,
which are included in this patch.
I tested 169 and 173 with a mt76 based USB dongle (AVM AC 860) and they
worked fine. If I saw that right, these channels are also covered by
register definitions inside the driver.
Channel 144 should also work, but gets disabled by the kernel as of now.

mt76 core uses ffs() to find the next free bit. This works well for 32 bit
architectures where BITS_PER_LONG is 32. ffs only checks 32 bit values, so
allocation fails on 64 bit architectures.
Additionally, the wcid mask array was too small in cases where the array
was not a multiple of BITS_PER_LONG.
Fix this by making the wcid mask array u32 instead and use DIV_ROUND_UP
for the size, just in case we ever bump it to a value that's not a multiple
of 32.
