Subject: [PATCH v2 0/4] media: cedrus: hevc: Add support for scaling matrix and multi-slice frames

Currently there is no control for HEVC scaling matrix and segment address
field is also missing. This series adds those and implements support for
them in Cedrus driver.

Following videos were used for testing:
- scaling matrix:

- multi-slice:

Best regards,
Jernej

Changes from v1:
- always set CTB_ADDR_X and CTB_ADDR_Y (patch 4)
