[U-Boot] [PATCH] AX88180: add support for the Marvell 88E1118 phy

[Mike Frysinger]

From: Hoan Hoang <hnhoan at i-syst.com>

Some places in the current code equate the Marvell 88E1111 PHY as the family
when in reality it's a subpart of the Alaska family.  So once we generalize
that, add support for the 88E1118 PHY.
