drm/i915: Fake HDMI live status
This patch does the following:
- Fakes live status of HDMI as connected (even if that's not).
While testing certain (monitor + cable) combinations with
various intel platforms, it seems that live status register
doesn't work reliably on some older devices. So limit the
live_status check for HDMI detection, only for platforms
from gen7 onwards.
V2: restrict faking live_status to certain platforms
V3: (Ville)
- keep the debug message for !live_status case
- fix indentation of comment
- remove "warning" from the debug message
(Jani)
- Change format of fix details in the commit message
