[PATCH v3 5/5] ARM: zynq: Add support for the Avnet Zedboard

[Steffen Trumtrar <s.trumtrar@pengutronix.de>]

The Avnet ZedBoard is an evalboard with a Zynq-7020 based MPSoC.
There is also a Digilent ZedBoard, that is the same but only for
academic customers.

Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de>

Changes since v2:
	- use pbl image
	- remove useless flash_header_start
