arm: socfpga: A5 SoCDK use environment in common header

This removes the default environment from the A5 socdk headers
and instead uses the common environment provided in
socfpga_common.h which now uses distro boot.

Add support to boot from the custom a2 type partition.

Change default devicetree name to match devicetree name in
upstream kernel source.
