Michal Simek f05131cd7a microblaze: Support simpleImage.dts make target
Instead of remembering to specify DTB= on the make commandline, this commit
allows the much friendlier make simpleImage.<dts>
where <dts>.dts is expected to be found in arch/microblaze/boot/dts/
The resulting vmlinux, with the compiled DTS linked in, will be copied to
boot/simpleImage.<dts>

This mirrors the same functionality as on PowerPC,
albeit achieving it in a slightly different way.

+ strip simpleImage file
The size of output file is very similar to linux.bin.

vmlinux - full elf without fdt blob
simpleImage.<dtb name>.unstrip - full elf with fdt blob
simpleImage.<dtb name> - stripped elf with fdt blob

Add symlink to generic system.dts in platform folder
