[igt-dev] [PATCH i-g-t 1/2] tests/kms_big_fb: Run the test for a single pipe only

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

I think we can safely assume that if no plane on the first
available pipe supports the format+mod+rotation combo we
don't have to check on all the other pipes.

The only slight exception is CHV where pipe B has a few more
features, but none of those are actually relevant for this
test.

Also leave put the PIPE_ANY commit as that still causes
pointless modesets.

$ time kms_big_fb
- real    2m8.101s
+ real    0m52.902s
