Hi

This test assumes that the case for a single kernel and single
RAM disk with no dtb is supported by kernel-fitimage.bbclass.
https://lists.openembedded.org/g/openembedded-core/message/140810 adds
support for this combination of usecase and the test wont pass without 
the usecase being supported.

Thanks,
Usama
