sh_eth: add sh_eth_cpu_data::cexcr flag
GEther controllers have CERCR/CEECR instead of CNDCR on the others.
Currently we are calling sh_eth_is_gether() in order to check for this,
however it would be simpler to check the new 'cexcr' bitfield in the
'struct sh_eth_cpu_data'; then we'd be able to remove sh_eth_is_gether()
as there would be no callers left...
