Davide Viti 03130f944a microzed: add Avnet Microzed support
Changes are based on Zedboard: Xilinx does not provide a specific DTS
for Microzed in the kernel tree. It is suggested [1] to use the
zynq-zed.dts and change the RAM size

[Thomas:
 - extend readme.txt to indicate why the same DTB is used for Microzed
   and the Zedboard.
 - add a description + Signed-off-by line in the
   0001-zynq-Create-microzed-specific-U-Boot-environment.patch, by
   re-using the description of the same patch for the Zedboard.]
