ACPI _LID methods may depend on OpRegions and do not always handle
handlers for those OpRegions not being present properly e.g. :

            Method (_LID, 0, NotSerialized)  // _LID: Lid Status
            {
                If ((^^I2C5.PMI1.AVBL == One) && (^^GPO2.AVBL == One))
                {
                    Return (^^GPO2.LPOL) /* \_SB_.GPO2.LPOL */
                }
            }

Note the missing Return (1) when either of the OpRegions is not available,
this causes (in this case) a report of the lid-switch being closed,
which causes userspace to do an immediate suspend at boot.

This commit delays getting the initial state and thus calling _LID for
the first time until userspace opens the /dev/input/event# node. This
ensures that all drivers will have had a chance to load and registerer
their OpRegions before the first _LID call, fixing this issue.
