The debug output for a HSW machine with two connectors (VGA and HDMI):

DEBUG: card0-VGA-1: mean.max 12896229,00ns, 12896,23us, 12,90ms, mean.avg 12785055,80ns, 12785,06us, 12,79ms
WARNING: card0-VGA-1: probe time exceed 10ms, max=12,90ms, avg=12,79ms
DEBUG: card0-HDMI-A-1: mean.max 781433,00ns, 781,43us, 0,78ms, mean.avg 706643,20ns, 706,64us, 0,71ms

v4:
- do not include the time opening the fd (Chris Wilson)
- include output from debug (Chris Wilson)

v3:
- use igt_mean for accounting (Chris Wilson)
- make it Intel-agnostic when searching for connectors (Chris Wilson)

v2:
- don't read cached values (Chris Wilson)
- warn on per connector, and fail per mean (Chris Wilson)

These are synthetic: 10ms per connector, and 50ms for all.
