Subject: wifi: mt76: mt7615: do not advertise 5 GHz on first phy of MT7615D (DBDC)
From: Paul Fertser <fercerpav@xxxxxxxxx>
commit 421033deb91521aa6a9255e495cb106741a52275 upstream.
On DBDC devices the first (internal) phy is only capable of using
2.4 GHz band, and the 5 GHz band is exposed via a separate phy object,
so avoid the false advertising.

Fixes: 7660a1bd0c22 ("mt76: mt7615: register ext_phy if DBDC is detected")
