drm/i915/dvo/sil164: Fix suspend/resume

Poke a few more bits into the SiI164 to make it
recover after S3. HEN/VEN are the important bits,
the rest PLL filter/HPD detection I just did
for good measure to match the BIOS programming.

Note that the spec recommended SCNT bit in REGC
isn't set by the BIOS at least for me, so I left
it out.
