From: Sean Wang <sean.wang@mediatek.com>

PHY offset in either .hw_value or .hw_value_short for mt7615, mt7663,
mt7915 and mt7921 device all start at bit 6, not 8.

Suggested-by: Ryder Lee <ryder.lee@mediatek.com>

v2: splitted out from the patch ("mt76: mt7921: fix mgmt frame using unexpected bitrate")
    to cover more devices which have the same issue.
v3: no change.

Unfortunately this patch causes a few regressions.
Since tx and rx handling is different in their use of the PHY mode bits,
the PHY part should of hw_value should be masked out when filling the tx
rateval. There are a few places in the code that rely on the fixed shift
of 8, including the generic function mt76_get_rate.
This patch should be dropped, and the bit offset differences dealt with
in the other patches of this series.
I will send an updated version
