drm/i915: fix panel fitting filter coefficient select for Ironlake

commit b1f60b7029989da71fd8ea1b1176480fac9e846c upstream.

Must set filter selection as hardcoded coefficients for medium 3x3
filtering, which matches vbios setting for Ironlake.

This fixes display corrupt issue on HP arrandale with new vbios.
