Move mt76x02_init_device routine in mt76x02_util.c in order to be
reused by mt76x0 driver and remove duplicated code. Move interface
combo definition supported by the driver in mt76x02_init_device routine

Is there some USB limitation that disallow tho do this for USB
as well? Or perhaps this is easer for now do this for PCI devices
and add AP support for USB later? But perhaps, since you adding
support for AP you could do this for both buses.
Thanks

AFAIK usb devices do not have TBTT interrupts so I think we can
use a timer to load beacon frames into the device. Anyway I guess
pre_tbtt_tasklet tasklet is something mmio specific.

in mt76x02_util.c in order to be reused by mt76x0 and mt76x2u drivers
