Enhances driver to use an MSI interrupt when available.

Adds the module option 'enable_msi' (type bool) which by default is
enabled. Can be set to 'N' to disable.

Fixes (or can reduce the occurrence of) a crash which is most commonly
reported when multiple saa7164 chips are in use. A reported example can
be found here:

I wanted to report that I have been running this patch for about a week now and I have had no instances of the zero free sequences issue.

Thank you very much!
