The maximum number of buffers depends of PAGE_SHIFT value and can go up to 0x7fff when PAGE_SHIFT = 12. With this encoding pattern we know the maximum number that a queue could store so we can check it at queue init time. It also make easier and faster to find buffer and plane from using the offset field. Change __find_plane_by_offset() prototype to return the video buffer itself rather than it index.

To know which entries of the bufs arrays are used a bitmap will be added in struct vb2_queue. That will also mean that the number of buffers will be computed given the number of bit set in this bitmap. To smoothly allow this evolution all drives must stop using directly num_buffers field from struct vb2_queue.

Create common helpers functions for these computation. Source and destination buffer height may not be the same because alignment constraint are different so use destination height to compute chroma offset because we target this buffer as hardware output. To be able to use the helpers in both VP9 HEVC code remove dec_params and use context->bit_depth instead.
