From: Sean Wang <sean.wang@xxxxxxxxxxxx>
add mt76_default_basic_rate to mt76 core more devices can rely on
to send frames which require the rate in the basic rates.

v3: created in v3 that is splitted out from the patch
("mt76: mt7921: fix mgmt frame using unexpected bitrate") v2
for more mt76 devices like mt7915 can reuse.
