[PATCH] ARM: zynq: add gem support

[Soren Brinkmann]

From: Steffen Trumtrar <s.trumtrar@xxxxxxxxxxxxxx>

The zynq includes a Cadence GEM IP core. This is compatible with the macb driver.
Add it to the zynq-7000 DT.

[soren: rebased to current Linus tree, added zc706 + zed support, moved phy-mode property to board level dtses]

This has a soft dependency on the net-next tree which has some patches for the
macb driver which are required for full functionality. But adding this patch to
any tree without net-next shouldn't do any harm, network might be
non-operational at the worst - I think.
