Subject: drm/i915: Add HP nx9020/SamsungSX20S to ACPI LID quirk list

From: Zhao Yakui <yakui.zhao@intel.com>

commit 40f33a92100f4d9b6e85ad642100cfe42d7ff57d upstream.

The HP comaq nx9020/Samsung SX20S laptop always report that the LID status is
closed and we can't use it reliabily for LVDS detection. So add the two boxes
into the quirk list.
