libfdt: Add new errors for the overlay code
Add a few new error codes to report the failure conditions we might
encounter in the overlay application code:
- FDT_ERR_BADOVERLAY, when an overlay cannot be parsed, even though its
structure is correct
- FDT_ERR_NOPHANDLES, when we ran out of available phandles and we
cannot use a new phandle without either using an invalid one (-1 or
0), or one already used.
