First, there is a single big endian format defined in `formats.yaml`: RGB565_BE.
However, while the yaml file specifies "big_endian: true", the python script
looks for a key named "big-endian". Causing `RGB565{,_BE}` both to be the same.
Second, the python script simply appends " | DRM_FORMAT_BIG_ENDIAN" to the
fourcc of the format. However, there is no definition of that macro is
available in the only user, `formats.h.in`.
Fix the first one by checking for "big_endian" in the script as well, and
fix the second one by defining a constant with the same value and using that.
