[PATCH 2/2 v2] drm/i915: Move DIV_ROUND_CLOSEST_ULL macro to header

["U. Artie Eoff" <ullysses.a.eoff@intel.com>]

Move the duplicated DIV_ROUND_CLOSEST_ULL macro into the intel_drv.h
header file so that it can be shared between intel_display.c
and intel_panel.c.

OTC-Jira: VIZ-4395

v2: Add reference to issue report in commit message.

Signed-off-by: U. Artie Eoff <ullysses.a.eoff@intel.com>
