Make it possible for data that was externalized using a static external position (-p) to be internalized. Enables the ability to convert existing FIT images built with -p to be converted to a FIT image where the data is internal, to be converted to a FIT image where the data is external relative to the end of the FIT (-E) or change the initial static external position to a different static external position (-p).
Removing the original external-data-related properties ensures that they're not present after conversion. Without this, they would still be present in the resulting FIT even if the FIT has been, for example, internalized.
Have checkpatch.pl skip warnings for use of fdtdec_* functions in tooling; livetree isn't used there.
