Andre Przywara 442ea3dd15 libfdt: fdt_offset_ptr(): Fix comparison warnings ...

With -Wsign-compare, compilers warn about mismatching signedness in
comparisons in fdt_offset_ptr().

This mostly stems from "offset" being passed in as a signed integer,
even though the function would not really tolerate negative values.

Short of changing the prototype, check that offset is not negative, and
use an unsigned type internally.
