[Intel-gfx] [PATCH i-g-t 2/3] tests/chamelium: Introduce fast CRC tests, with a single mode

[Paul Kocialkowski]

This introduces a fast fashion of testing display CRC, that only tests
a single mode (the highest resolution). It drastically reduces the run
time of the test, which is necessary for the fast-feedback test list.
