sh_eth: get rid of 'sh_eth_cpu_data::shift_rd0'
After checking all the available manuals, I have enough information to
conclude that the 'shift_rd0' flag is only relevant for the Ether cores
supporting so called "intelligent checksum" (and hence having CSMR) which
is indicated by the 'hw_crc' flag. Since all the relevant SoCs now have
both these flags set, we can at last get rid of the former flag...
