[Intel-gfx] [PATCH 0/2] Live status detection fixes

With the introduction of the extended timeouts for live status
detection to accomodate for displays that does not immediately
answer to live status requests, we also introduced rather large
overhead whenever we run intel_hdmi_detect() -- the overhead
is multiplied by the number of HDMI-ports.

The first patch here skips the live status check completely for
platforms where the results are unreliable (without the patch
we'd do the check, then ignore the result). The second patch
removes the extended timeouts by default, but offers options
to either use the extended timeouts, or completely disable
live status check.
