boot: Support compressed booti images in bootm
A compressed booti image relies on the compression-format's header at
the start to indicate which compression algorithm is used.
We don't support this elsewhere in U-Boot, so assume that a compressed
file is always a booti file. Once it is compressed, a check is made to
make sure that it actually is.
Simplify the implementation by adding a new function which returns the
booti image-type if compression is detected.
