Subject: [PATCH] drm/i915: blacklist lid status: Sony VGN-BX196VP, Dell Inspiron 700m

BugLink: https://bugs.launchpad.net/bugs/515246

Sony VGN-BX196VP and Dell Inspiron 700m report lid status as closed
when it is open. This leads to a "no connectors reported" error at startup.
Blacklisting them, to always return a connected status for the default
lvds connector.

Due to lack of hardware, I have not tested this patch on my own. Further
testing shall be helpful.
