dt: dt-check-compatible: Find struct of_device_id instances with compiler annotations

Browse Source 
The regex search for declarations of struct of_device_id was missing
cases that had a compiler annotation such as "__maybe_unused". Improve
the regex to allow for these. Use '\S' instead of specific characters to
shorten the regex. That also finds some more compatibles using '.'
characters.

Unfortunately, these changes add ~400 more compatibles without a
schema.
