i965: Fix typos in license

grep -lr 'sub license' | while read f; do \
    sed --in-place -e 's/sub license/sublicense/' $f ;\
    done

grep -lr 'NON-INFRINGEMENT' | while read f; do \
    sed --in-place -e 's/NON-INFRINGEMENT/NONINFRINGEMENT/' $f ;\
    done

As noted by Matt, both of these changes match the MIT license text found
