From: Vladimir Barinov <vladimir.barinov@xxxxxxxxxxxxxxxxxx>
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@xxxxxxxxxxxxxxxxxx>
[Sergei: some macro/comment cleanup; updated the copyrights, removed duplicate
#include, annotated all platform data as '__initdata', added a сheck for the
'sh_eth' driver being enabled before registering VIN1 due to a pin conflict,
removed superfluous semicolon after iclink[01]_ml86v7667' initializer.]

Changes since version 5:
- resolved reject, refreshed the patch.
Changes since version 4:
- added a сheck for the 'sh_eth' driver being enabled before registering VIN1
due to a pin conflict;
- removed superfluous semicolon after iclink[01]_ml86v7667' initializer;
- resolved rejects, refreshed the patch.
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.
