====================
sh_eth: unify the SoC feature checks

Here's a set of 5 patches against DaveM's 'net-next.git' repo.

The Ether driver sometimes uses the bit fields in 'struct sh_eth_cpu_data'
to check which Ether registers exist in a certain SoC and sometimes it uses
sh_eth_is_{gether|rz_fast_ether}() which basically compares 2 pointers (1 of
them being constant) -- the latter is definitely not a strongest feature of
the RISC CPUs (be it SH or ARM), so I decided to get rid of this type of
the feature checks in favour of the bit fields (I've also made use of a
32-bit value and method pointer where appropriate)...

[1/5] sh_eth: add sh_eth_cpu_data::soft_reset() method
[2/5] sh_eth: add sh_eth_cpu_data::edtrr_trns value
[3/5] sh_eth: add sh_eth_cpu_data::xdfar_rw flag
[4/5] sh_eth: add sh_eth_cpu_data::no_tx_cntr flag
[5/5] sh_eth: add sh_eth_cpu_data::cexcr flag
