[PATCH] checkpatch.pl: adapt to new Assisted-by: format

[Jeff Layton]

There is a new format for the 'Assisted-by:' tag. Change checkpatch.pl
to just check that it has a value rather than testing for a specific
format.

Assisted-by: LLM
Signed-off-by: Jeff Layton <jlayton@xxxxxxxxxx>

This is a companion patch to the one to change the format in
Documentation/. See:
