A number of KMS tests are using checks like "igt_assert(x < y)" rather
than using the dedicated comparison assertions that print the actual
values on assertion failure. Run all KMS tests through Coccinelle to
apply these conversions and also apply some other general coding style
cleanup:

       spatch --in-place --sp-file lib/igt.cocci tests/kms_*
       spatch --in-place --sp-file lib/igt.cocci tests/intel/kms_*
       spatch --in-place --sp-file lib/igt.cocci tests/testdisplay*
       spatch --in-place --sp-file lib/igt.cocci tests/fbdev.c
