[Intel-gfx] [PATCH 4/6] drm/i915: Use msecs_to_jiffies_timeout when waiting for Punit freq change

[ville.syrjala at linux.intel.com]

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

The timeout is 10 ms so it would end up as one jiffy when HZ=100, and
one jiffy is quite susceptible to spurious timeouts as we've seen
recently.
