It is useful to be able to flash Edison directly without relying on the
installed U-Boot being functional.

Add a binman image for this. It includes a 'OSIP' header (which happens to
look like an MBR / (Master-Boot Record), U-Boot binary and an environment.

I am not able to find a specification for OSIP.
