[RFC PATCH v2 2/3] dtc: make check test for dtc --annotate

[Frank Rowand <frowand.list-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Frank Rowand <frank.rowand-/MT0OVThwyLZJqsBc5GL+g@public.gmane.org>

Add dtc tests.

  - dtc --annotate to create a .dts with annotations
  - compile the annotated .dts
  - compare the .dts created from include0.dts to the .dts created
    by first compiling include0.dts with annotations, then compiling
    the resulting .dts without --annotations to strip the annotation
