Subject: [PATCH v6 0/6] media: iris: port support for Qualcomm SC7280

Port Support for the Qualcomm SC7280 aka QCM6490 aka QCS6490 platform
from the existing venus driver to the newer Iris driver. The firmware on
this platform uses the older, gen1 HFI, which puts it close to SM8250
from both the hardware and interface point of view.

Test results:

$ ./fluster.py r -d GStreamer-H.264-V4L2-Gst1.0 -ts JVT-AVC_V1
...
Ran 76/135 tests successfully               in 16.903 secs

$ ./fluster.py r -d GStreamer-H.265-V4L2-Gst1.0 -ts JCT-VC-HEVC_V1 -j 1

Only WPP_E_ericsson_MAIN_2 succeeds, this needs to be investigated
later. For other tests I'm getting:

qcom-iris aa00000.video-codec: session error for command: db800000, event id:1009, session id:4bd48000

After removing several test vectors and running single-threaded:
$ ./fluster.py r -d GStreamer-VP9-V4L2-Gst1.0 -ts VP9-TEST-VECTORS -j 1
Ran 217/292 tests successfully               in 136.210 secs

Disabled tests:
