[Intel-gfx] [PATCH i-g-t] tests/kms_fbc_crc: Don't force fbc on old platforms

[Daniel Vetter]

It's simply a bit too scary on pre-gen6 and imo not worth the bother
really until someone starts to implement all the hacks an w/a required
on these platforms. On later platforms the issues are just with
correctness and performance hence no risk for hanging machines.
