[media] V4L2: soc_camera: Renesas R-Car VIN driver

Browse Source 
Add Renesas R-Car VIN (Video In) V4L2 driver.
Based on the patch by Phil Edworthy <phil.edworthy@renesas.com>.
[Sergei: removed deprecated IRQF_DISABLED flag, reordered/renamed 'enum chip_id'
values, reordered rcar_vin_id_table[] entries,  removed senseless parens from
to_buf_list() macro, used ALIGN() macro in rcar_vin_setup(), added {} to the
*if* statement  and used 'bool' values instead of 0/1 where necessary, removed
unused macros, done some reformatting and clarified some comments.]
