[PATCH v4 2/3] ARM: shmobile: BOCK-W: add VIN and ML86V7667 support

[Sergei Shtylyov]

From: Vladimir Barinov <vladimir.barinov at cogentembedded.com>

Add ML86V7667 platform devices on BOCK-W board, configure VIN0/1 pins, and
register VIN0/1 devices with the ML86V7667 specific platform data.

Signed-off-by: Vladimir Barinov <vladimir.barinov at cogentembedded.com>
[Sergei: some macro/comment cleanup; updated the copyrights, removed duplicate
#include, annotated all platform data as '__initdata'.]

Changes since version 3:
- changed the VIN platform device names to be R8A7778 specific; 
- resolved reject due to USB patch rework, refreshed the patch.

Changes since version 2:
- removed duplicate #include <linux/pinctrl/machine.h>;
- annotated all platform data as '__initdata' since they're kmemdup()'ed while
  registering the platform devices anyway;
- resolved rejects, refreshed the patch.
