drm/i915: Compute WR PLL dividers dynamically

Up to now, we were using a static table to match the clock frequency
with a (r2,n2,p) triplet. Despite this table being big, it's by no mean
comprehensive and we had to fall back to the closest frequency when the
requested TMDS clock wasn't in the table.

This patch computes (r2,n2,p) dynamically and get rid of The Big Table.

v2: Replace the floating point constant 1e6 by 1000000
