Subject: [PATCH v2 0/8] 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 77/135 tests successfully               in 17.010 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

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 219/292 tests successfully               in 134.749 secs

Changes in v2:
- Expanded commit messages to explain some of the changes (Konrad).
- Moved platform_inst_cap_qcs8300 back to the header (Dikshita) and
  added guarding ifdefs to the haders.
- Merged SC7280-specific ops into the common implementations (Konrad).
- Split SC7280-specific config bits to a separate header (following the
  Gen2 split).
- Link to v1: https://lore.kernel.org/r/20251008-iris-sc7280-v1-0-def050ba5e1f@oss.qualcomm.com
