drm/i915: Bump timeout for wait_for_engines()

Extract the timeout we use in i915_gem_idle_work_handler() and reuse it
for wait_for_engines() in i915_gem_wait_for_idle(). It too has the same
problem in sometimes having to wait for an extended period before the HW
settles, so make use of the same timeout.
