Add variant to IMX8M to enable G2/HEVC codec.
Define the capabilities for the hardware up to 3840x2160.
G2 doesn't have postprocessor, use the same clocks and got it
own interruption.

Add variant to IMX8M to enable G2/HEVC codec.
Define the capabilities for the hardware up to 3840x2160.
G2 doesn't have postprocessor, use the same clocks and got it
own interruption.

version 8:
- Add Ezequiel Reviewed-by tag.
version 7:
- Add Philipp Reviewed-by tag.
version 5:
- remove useless postproc fields for G2
version 2:
- remove useless clocks
