[PATCH 1/2] Enable codespell from config file.

[Michael Santana <msantana@redhat.com>]

Enable turning on codespell from any of the config files for
checkpatches.sh. codespell is a feature by checkpatch.pl that
checks for common spelling mistakes in comments in patches.

This feature is disabled by default. To enable it one must add
the '--codespell' flag to the $options variable in
checkpatches.sh. With this change the user can decide to turn
on codespell from a config file rather than directly modifying
checkpatches.sh
