mtd: m25p80: Fix the Spansion chip detection
Due to the implementation of the following loop at the end
of jedec_probe():
776 for (tmp = 0; tmp < ARRAY_SIZE(m25p_ids) - 1; tmp++) {
777 info = (void *)m25p_ids[tmp].driver_data;
778 if (info->jedec_id == jedec) {
779 if (info->ext_id != 0 && info->ext_id != ext_jedec)
780 continue;
781 return &m25p_ids[tmp];
782 }
783 }
In particular line 779 in the above numbering, the chips with ext_id != 0 must
be ordered first in the list of chips (m25p_ids[]).
