Yeah, I think just including libfdt.h instead of fdt.h is the way to
go.  The distinction is that fdt.h contains only "passive"
declarations.  That is, defines and structure/type declarations but no
function prorotypes or other code.  In particular that means that it
is strictly about the FDT tree structure only, and not any of the
libfdt specific entry points.
