[PATCH 1/3][v2] net: phy: introduce 1000BASE-KX and 10GBASE-KR

[<shh.xie@gmail.com>]

From: Shaohui Xie <Shaohui.Xie@freescale.com>

This commit adds necessary definitions for the PHY layer to recognize
backplane Ethernet 1000BASE-KX and 10GBASE-KR as valid PHY interfaces,
"1000base-kx" for 1000BASE-KX, "10gbase-kr" for 10GBASE-KR.
