drm/i915: disable opregion lid detection for now
but leaves the autodetect mode disabled. There's also the explicit lid
status option added in

drm/i915: Add a module parameter to ignore lid status
Which overloaded the meaning for the panel_ignore_lid parameter even
more. To fix up this mess, give the non-negative numbers 0,1 the
original meaning back and use negative numbers to force a given state.
So now we have
1 - disable autodetect, return unknown
0 - enable autodetect
-1 - force to disconnected/lid closed
-2 - force to connected/lid open
v2: My C programmer license has been revoked ...
v3: Beautify the code a bit, as suggested by Chris Wilson.
