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