[PATCH v2 2/2] ARM: shmobile: R8A7778: add Ether support

[Kuninori Morimoto]

Hi

> Add Ether clock and platform device for R8A7778 SoC; add a function to register
> this device with board-specific platform data.

> This patch is atop of the 'renesas-next-20130404v2' tag of Simon Horman's
> 'renesas.git'.
> 
> Changes since original posting:
> - use 'struct sh_eth_plat_data *' as an argument to r8a7778_add_ether_device();
> - use platform_device_register_resndata() in r8a7778_add_ether_device().
