net: phy: dp83822: disable MDI crossover status change interrupt

Browse Source 
[ Upstream commit 7f378c03aa4952507521174fb0da7b24a9ad0be6 ]

If the cable is disconnected the PHY seems to toggle between MDI and
MDI-X modes. With the MDI crossover status interrupt active this causes
roughly 10 interrupts per second.

As the crossover status isn't checked by the driver, the interrupt can
be disabled to reduce the interrupt load.
