[ Upstream commit f75ca32403dbf91e20c275719aab705401b9e718 ]
When adding the sh_eth_cpu_data::cexcr flag I forgot to add the flag check to __sh_eth_get_regs(), causing the non-existing RX packet counter registers to be considered for dumping on the R7S72100 SoC (the register offset sanity check has the final say here)...
