Thanks to Miguel, there is finally a NAND driver for this SoC and we can
now support the NAND device on the EBAZ4205.

Btw. I'm not sure how often the PL35x NAND controller is used in SoC and
if it qualifies to add it to the multi_v7 defconfig.

After years, linux finally got a driver for the PL35x NAND controller
found on the Xilinx Zynq-7000 SoC for example. Enable support for this
driver.

Recently, a driver for the ARM Primecell PL35x static memory controller
(including NAND controller) was added in linux. Add the corresponding
device tree node.

The board features a 128MiB NAND chip and recently linux gained support
for the NAND controller on the Zynq SoC. Thus add the corresponding
devicetree nodes.
