Hello,

This patch series aims to bring H.264 support as well as compliance update
to the amlogic stateful video decoder driver.

The issue in the V1 patchset at [1] is solved by patch #1 following comments
and requirements from hans.

With this, it passes v4l2-compliance with streaming on Amlogic G12A and
Amlogic SM1 SoCs successfully.

This patchset depends on G12A and SM1 enablement series at [2] and [3].

The compliance log is:
# v4l2-compliance --stream-from-hdr test-25fps.h264.hdr -s 200
v4l2-compliance SHA: 7ead0e1856b89f2e19369af452bb03fd0cd16793, 64 bits

Compliance test for meson-vdec device /dev/video0:

Changes since v1 at [1]:
- fixed output_size is never used reported by hans
- rebased on G12A and SM1 patches
- added handling of qbuf after STREAMON and STOP before enought buffer queued
