Introduce extended utility routines to read/write data o usb bus. New
devices (e.g. mt7663u) will rely on both upper and lower part of the
register address. Add ext parameter to mt76u_init signature in order to
reuse the code adding mt7663u support.

rate controller and throughput are very sensitive to tx status timing.
In order to improve performances when the system is heavily loaded,
substitute stat_work delayed_work with a regular work_struct and create
a mt76u dedicated workqueue for tx status reporting

mt76x{0,2}u is now registering through usb_device. Fix it by passing
usb_intf device to mt76_alloc_device routine.

Since some USB device IDs are duplicated between mt76x0u, mt7601u
and mt76x2u device, check chip version on probe and return error if
not match the driver.
Don't think this is serious issue, probe most likely will fail at
some other point for wrong device, but we do not have to configure
it if we know is not our device.

Use usb_bulk_msg for reading MCU command responses. This simplify code
a lot.
Together with 97a3005759c ("mt76usb: allow mt76u_bulk_msg be used
for reads") it also fix possible problems with rx data buffers
not being aligned and contained within single page. After doing
page_frag_alloc(1024) consecutive page_frag_alloc(PAGE_SIZE) will
alloc PAGE_SIZE buffer at PAGE_SIZE - 1024 offset.
