net: bcmgenet: Set phydev->dev_flags only for internal PHYs

BugLink: https://bugs.launchpad.net/bugs/1850456
[ Upstream commit 92696286f3bb37ba50e4bd8d1beb24afb759a799 ]

phydev->dev_flags is entirely dependent on the PHY device driver which
is going to be used, setting the internal GENET PHY revision in those
bits only makes sense when drivers/net/phy/bcm7xxx.c is the PHY driver
being used.
