net: phy: at803x: simplify custom phy id matching

Browse source

The at803x driver contains a function, at803x_match_phy_id(), which
tests whether the PHY ID matches the value passed, comparing phy_id
with phydev->phy_id and testing all bits that in the driver's mask.

This is the same test that is used to match the driver, with phy_id
replaced with the driver specified ID, phydev->drv->phy_id.

Hence, we already know the value of the bits being tested if we look
at phydev->drv->phy_id directly, and we do not require a complicated
test to check them. Test directly against phydev->drv->phy_id instead.
