[PATCH RFT v2] net: sh_eth: add support for SH7786

[Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>]

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

This commit adds the sh_eth_cpu_data structure that describes the
SH7786 variant of the IP.

Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

The patch is against DaveM's 'net-next.git' repo.
Not posting it to netdev@vger.kernel.org this time since the 'net-next' repo
is still closed.

Changes in version 2:
- added a comment before 'sh7786_data' initializer;
- added now mandatory soft_reset() method;
- changed the 'register_type' initializer to SH_ETH_REG_FAST_RCAR;
- added the 'ecsr_value' field initializer;
- renamed EESR_RTO to EESR_TRO;
- added the 'fdr_value' field initializer;
- added the 'no_xdfar'  field initializer.
