To: intel-gfx; +Cc: jani.nikula, Dave Airlie
From: Dave Airlie <airlied@redhat.com>
This pulls a large chunk of the pll calculation code out of
intel_display.c to a new file.
One function makes sense to be an inline, otherwise this
is pretty much a straight copy cover. Also all the
remaining hooks for g45 and older end up the same now.
