This allows to use any available compression format with Android boot image
Since not all available compression formats have a magic number we should explicitly specify type of compression.
For this purpose using uImage format becomes very useful, as this format is well-known by the community and mkimage tool is already available.
Usage example: mkimage -A ARM64 -T kernel -C lzma -d Image.lzma out/kernel
At this moment only -C option is handled, but specifying -A and -T options are recommended for compatibility reasons in the future.
Kernel that compressed with LZ4 can be already used without wrapping into the uImage, but I recommend wrapping it into the uImage in order to avoid situations when by some mistake legacy LZ4 is used, that is interpreted as raw Image and causes CPU to enter Exception Handler without providing any meaningful explanation to the user.

Applied to u-boot/master, thanks!
