drm/i915: Use round to closest when computing the CEA 1.001 pixel clocksdrm-intel-next-fixes-2015-10-22
drm_edid.c now computes the alternate CEA clocks using
DIV_ROUND_CLOSEST(), so follow suit in the N/CTS setup to make sure we
pick the right setting for the mode.
Unfortunately we can't actually use DIV_ROUND_CLOSEST() here due to the
({}) construct used, so just stick in raw numbers instead.
