[PATCH 4/6] net: phy: maxio: extend PHY ID matching

Message-ID <[email protected]>
Currently the maxio Ethernet PHY driver expects a PHY matching exactly the
one ID provided: 0x7b744412. The Maxio MAE0621A-Q3C model used on
the Allwinner based X96QPro+ TV box uses a slightly different PHY ID:
0x7b744411.

Replace the "exact match" requirement with the more relaxed "model
match" version, which ignores the lowest 4 bits of the PHY ID. Both
PHYs should now be recognised by the driver.
