[media] ARM: shmobile: r8a7779: add VIN support

Browse source 
Add VIN clocks and platform devices for R8A7779 SoC; add function to register
the VIN platform devices.
[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'.]
