VC8000D decodes only to 4x4 tiled NV12 format and the attached PP
can be used to de-tile its output. This can bo done in two modes:

1. Pipeline mode, using the same decoder "done" irq
2. External mode, with a separate irq and input setup.

This adds the relevant postprocessor fields and support for pipeline
mode de-tiling.
