Update .checkpatch.conf

- Don't require a description of every config statement in the
Kconfig changes
- Don't complain about externs in .c files
- Don't complain about the use of the volatile keyword.  The kernel
may not want it, but we definitely need it.
- Disable checks that seem to be broken.
