[PATCH 2/6] ibm_newemac: Add ET1011c PHY support

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

This adds support for the ET1011c PHY as found on the taishan
board.

The code comes from the kernel distributed with the board by
AMCC and developped by DENX.

Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

And don't ask me about using phylib, it's in plan :-)
