media: rcar-vin: Move hardware buffer tracking to own struct
To support SEQ_TB/BT not all buffers given to the hardware will be
equal, the driver needs to keep track of different buffer types. Move
the tracking of buffers given to hardware into a struct so additional
tracking fields can be associated with each buffer.
