[GIT PULL FOR v5.14] Add HANTRO G2/HEVC decoder support for IMX8MQ

[Hans Verkuil <hverkuil@xs4all.nl>]

Note: there is one checkpatch warning about an undocumented DT compatibility string:

WARNING: DT compatible string "nxp,imx8mq-vpu-g2" appears un-documented -- check ./Documentation/devicetree/bindings/
#29: FILE: drivers/staging/media/hantro/hantro_drv.c:591:
+       { .compatible = "nxp,imx8mq-vpu-g2", .data = &imx8mq_vpu_g2_variant },

This will go through another subsystem, as this is related to power domain changes, see:

Since that's independent of the HEVC support, and this is still staging, I did
not want to hold back this series.

Regards,

	Hans
