bootm: make use of legacy image format configurable
make the use of legacy image format configurable through
the config define CONFIG_IMAGE_FORMAT_LEGACY.
When relying on signed FIT images with required signature check
the legacy image format should be disabled. Therefore introduce
this new define and enable legacy image format if CONFIG_FIT_SIGNATURE
is not set. If CONFIG_FIT_SIGNATURE is set disable per default
the legacy image format.
