How much does this size difference and decompression affect boot times?

Instead of adding Makefile targets and custom binman etypes adding
support for on-the-fly compression to the fit etype if probably a better
option. E.g. when fit node has compression <> none, compress the data content
inside binman instead of relaying on binman nodes and Makefile output.
