[Intel-gfx] [maintainer-tools PATCH v2] dim: Check for required tags as part of dim_checkpatch

[Imre Deak]

Check in dim_checkpatch if the committer's Signed-off-by line and a
Reviewed-by line exists in the commit message. If no Reviewed-by line
exists also accept two distinct Signed-off-by lines instead.

v2: (Jani)
- move the check from dim_push_branch to dim_checkpatch
- remove the check for the author's Signed-off-by line
- in case there is no Reviewed-by line also accept two distinct
  Signed-off-by lines
