drm/i915: Disable infoframes when shutting down DDI HDMI
Disabling the video DIP when shutting the port down seems like a good
idea.
Bspec says:
"When disabling both the DIP port and DIP transmission,
first disable the port and then disable DIP."
and
"Restriction : GCP is only supported with HDMI when the bits per color is
not equal to 8. GCP must be enabled prior to enabling TRANS_DDI_FUNC_CTL
for HDMI with bits per color not equal to 8 and disabled after disabling
TRANS_DDI_FUNC_CTL"
So let's do it in the .post_disable() hook.
v2: Remove double "dpms off" caused by rebase fail
