[PATCH 1/2] SolutionEngine771x: fix Ether platform data

[PATCH 1/2] SolutionEngine771x: fix Ether platform data

[Sergei Shtylyov]

The 'sh_eth' driver's probe() method would fail  on the SolutionEngine7710
board and crash on SolutionEngine7712 board  as the platform code is
hopelessly behind the driver's platform data --  it passes the PHY address
instead of 'struct sh_eth_plat_data *'; pass the latter to the driver in
order to fix the bug...

Fixes: 71557a37adb5 ("[netdrvr] sh_eth: Add SH7619 support")

The patch is against Paul Mundt's 'linux-sh.git' repo, 'sh-latest' branch.

    Now that I was finally able to build an SH kernel, I realized that I 
forgot to add #include <linux/sh_eth.h>... :-/
