[PATCH 06/10] drm/i915: Use a 1 second timeout for the polling vblank wait

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

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

40 msec seems like a very random number for a vblank wait timeout.
Considering ~24Hz display modes are definitely a thing this seems
way too low. Just bump it to a full second to match what we've been
using for normal vblank waits.
