[igt-dev] [PATCH i-g-t 1/4] tests/kms_frontbuffer_tracking: Add tiling to test_mode

["José Roberto de Souza" <jose.souza@intel.com>]

This will allow us to do tests with different tile types, for now
all tests will continue to run with the default X tiling.

It also allow user to run all tests with liner tiling when set by
parameter.
