[PATCH v5 1/3] ARM: shmobile: r8a7779: add VIN support

From: Vladimir Barinov <vladimir.barinov at cogentembedded.com>
Add VIN clocks and platform devices for R8A7779 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 r8a7779_add_vin_device(), used '*pdata'
in *sizeof* operator there, renamed some variables, annotated vin[0-3]_resources
[] and 'vin[0-3]_info' as '__initdata'.]

Changes since version 4:
- resolved reject.
Changes since version 3:
- changed the VIN platform device name to be R8A7779 specific;
- used '*pdata' in *sizeof* operator in r8a7779_add_vin_device();
- resolved reject in <mach/r8a7779.h> due to USB patch rework.
Changes since version 2:
- annotated vin[0-3]_resources[] and 'vin[0-3]_info' as '__initdata' since they
are kmemdup()'ed while registering the platform devices anyway;
Changes since the original posting:
- added 'id' parameter check to r8a7779_add_vin_device().
