Subject: [PATCH net-next 4/7] net: phy: marvell10g: 88x3310 and 88x3340 don't support isolate mode

The 88x3310 and 88x3340 PHYs don't support the isolation mode,
regardless of the MII mode being used
(SGMII/1000BaseX/2500BaseX/5GBaseR/10GBaseR). Flag this in the driver.

This was confirmed on the 88x3310 on a MacchiatoBin.
