Gzip compression is not part of the distro boot spec, therefore the kernel needs to be delivered in uncompressed form.

64bit U-Boot prefixes fdtfile with 'broadcom/'.

As flash-kernel will copy the dtb both to

    dtbs/${VERSION}/ and
    dtbs/${VERSION}/broadcom/

adding the prefix in the database won't harm 32bit U-Boot installations.
