drm/i915: Align the hangcheck wakeup to the nearest second
round_jiffies() aligns the wakeup time to the nearest second in order to
batch wakeups and reduce system load, which is useful for unimportant
coarse timers like our hangcheck.
v2: round_jiffies_relative() returns the relative jiffie value, whereas
we need the absolute value for the timer.
