[PATCHv7 5/5] arm64: Hook up the ZBOOT support as vmlinuz

From: Jeremy Linton <jeremy.linton at arm.com>

Add the previously defined _probe() and _usage() routines
to the kexec file types table, and build the new module.

It should be noted that this "vmlinuz" support reuses the
"Image" support to actually load the resulting image after
it has been decompressed to a temporary file.
