PATCH v3 1/1 ARM: shmobile: BOCK-W: add Ether support

Register Ether device from bockw_init(), passing the platform data to it, adding only the RMII pin group to bockw_pinctrl_map[]. Although the LINK signal exists on the board, it's connected to the link/activity LED output of the PHY, thus the link disappears and reappears after each packet. We'd be better off ignoring such signal and getting the link state from the PHY indirectly.

---
The patch is atop of Simon's 'renesas.git' repo, 'renesas-next-20130528' tag and the USB patches just reposted. I decided to move it ahead of the VIN patches as it can be merged right now since all dependecies have been already met.

Changes from version 2:
- resolved rejects due to patch move;
- removed the code dealing with the pin conflict with VIN1 and the note related to it from the changelog.

Changes from the original posting:
- refreshed the patch.

Has this been pulled by Olof/Arnd? If not, is it possible to amend
this patch or should I send an incremental one? I forgot to update the platform device name from "sh-eth" to "r8a777x-ether" in the PinMux table, in accordance to the R8A7778 Ether device name fix. It would be good if this got into 3.11 as otherwise Ether support on BOCK-W wouldn't work. I have discovered the mistake only yesterday.

WBR, Sergei

This patch is not present in arm-soc nor have I sent a pull request for it, though I was planing to do so today.

I think that the best thing would be if you sent an incremental patch which I can add to the boards branch and then send a pull-request for that branch to Olof and Arnd.

Darn, I should have changed that to "r8a777x-ether" in view of the
changes queued in the 'net-next.git' repo and the v2 of the "fix Ether device name" patch. I've completely overlooked that...
