[PATCH v2 00/12] media: rkvdec: Add support for VDPU381 and VDPU383

[Detlev Casanova <detlev.casanova@collabora.com>]

These variants are found respectively in the RK3588 and RK3576 SoCs.
This patch only adds support for H264 and H265 in both variants.

As there is a considerable part of the code that can be shared with the
already supported rkvdec decoder driver, the support for these variants
is added here rather than writing a new driver.

This patch set uses the newly introduced hevc_ext_sps_[ls]t_rps v4l2
controls for HEVC [1].
Therefore, a patched version of userpace tools is needed for HEVC
support (added for GStreamer[2] and in an early stage for FFmpeg[3]).

This patch set also depends on the preparation patch set sent earlier [4]
as well as the iommu restore fix [5] (already merged in linux-media) and
Nicolas Frattaroli's bitmap patch [6] to support setting registers that
uses upper 16 bits as masks.

Changes since v1:
 - Add parsing of the short and long term ref frame sets from the new v4l2
   controls
 - Add RPS cache to avoid parsing the same data again
 - Fix HEVC pixel formats selection
 - Fix multiple indentation errors
