[PATCH v6 1/3] ARM: shmobile: r8a7778: add VIN support

[Sergei Shtylyov]

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

Add VIN clocks and platform devices on R8A7778 SoC; add function to register
the VIN platform devices.

Signed-off-by: Vladimir Barinov <vladimir.barinov at cogentembedded.com>
[Sergei: added 'id' parameter check to r8a7778_add_vin_device(), used '*pdata'
in *sizeof* operator, and added an empty line there; renamed some variables,
annotated 'vin[01]_info' and vin[01]_resources[] as '__initdata'.]

Changes since version 5:
- added an empty line in r8a7778_add_vin_device();
- resolved reject, refreshed the patch.

Changes since version 4:
- resolved reject, refreshed the patch.

Changes since version 3:
- changed the VIN platform device names to be R8A7778 specific; 
- resolved reject in <mach/r8a7778.h>  due to USB patch rework.

Changes from version 2:
- annotated 'vin[01]_info' and vin[01]_resources[] as '__initdata' since they're
  kmemdup()'ed while registering the platform devices anyway;
- refreshed the patch.
