sh_eth: add sh_eth_cpu_data::gecmr flag
Not all Ether controllers having the Gigabit register layout have GECMR -- RZ/A1 (AKA R7S72100) actually has the same layout but no Gigabit speed support and hence no GECMR. In the past, the new register map table was added for this SoC, now I think we should have used the existing Gigabit table with the differences (such as GECMR) covered by the mere flags in the 'struct sh_eth_cpu_data'. Add such flag for GECMR -- and then we can get rid of the R7S72100 specific layout in the next patch...
