If 'irq_of_parse_and_map()' or 'of_address_to_resource()' fail, 'err' is
known to be 0 at this point.
So return -ENODEV instead in the first case and use 'of_iomap()' instead of
the equivalent 'of_address_to_resource()/ioremap()' combinaison in the 2nd
case.
Doing so, the 'rsrc_regs' field of the 'emac_instance struct' becomes
redundant and is removed.
