[0/6] H6 Cedrus support

This patch series adds basic support for H6 VPU. VPU itself has some new
features like 10-bit HEVC decoding, support for AFBC output format when
decoding HEVC and IOMMU. However, none of that is currently implemented.

Please take a look.

Best regards,
Jernej

Applied, thanks!

Looks like the patch adding SRAM support made it through but this one
didn't. It looks ready to be picked up though.
