drm/i915: add WR PLL programming table 



This table is used for programming WR PLL clocks, used by HDMI and DVI outputs.
I split it into a separate patch to simplify the HDMI enabling patch which was
getting huge.

Note that this table is a temporary solution for WR PLL programming. It
will be reworked into a more exact algorithm at a later stage. But for
now, it provides the most accurate clock setting solution, so we use it
here.
