[PATCH v5 02/10] hantro: postproc: Introduce struct hantro_postproc_ops

Andrzej Pietrasiewicz

From: Ezequiel Garcia <ezequiel@collabora.com>

Turns out the post-processor block on the G2 core is substantially
different from the one on the G1 core. Introduce hantro_postproc_ops
with .enable and .disable methods, which will allow to support
the G2 post-processor cleanly.
