[ Upstream commit 77e9a4aa ]

More and more platforms need the button.lid_init_state=open quirk. This
patch sets it the default behavior.

If a platform doesn't send lid open event or lid open event is lost due to
the underlying system problems, then we can compare various combinations:
1. systemd/acpid is used to suspend system or not, systemd has a special
   logic forcing open event after resuming;
2. _LID returns a cached value or not.

The result is as follows:

 1. lid_init_state=method
   1. cached
      1. resumed by lid:
         (x) event=close
         (x) systemd=suspends again
         (x) acpid=suspends again
         (x) state=close
      2. resumed by other:
         (o) event=close
         (x) systemd=suspends again
         (x) acpid=suspends again
         (o) state=close
   2. non-cached
      1. resumed by lid:
         (o) event=open
         (o) systemd=resumes
         (o) acpid=resumes
         (o) state=open
      2. resumed by other:
         (o) event=close
         (x) systemd=suspends again
         (x) acpid=suspends again
         (o) state=close
 2. lid_init_state=open
   1. cached
      1. resumed by lid:
         (o) event=open
         (o) systemd=resumes
         (o) acpid=resumes
         (x) state=close
      2. resumed by other:
         (x) event=open
         (o) systemd=resumes
         (o) acpid=resumes
         (o) state=close
   2. non-cached
      1. resumed by lid:
         (o) event=open
         (o) systemd=resumes
         (o) acpid=resumes
         (o) state=open
      2. resumed by other:
         (x) event=open
         (o) systemd=resumes
         (o) acpid=resumes
         (o) state=close
 3. lid_init_state=ignore
   1. cached
      1. resumed by lid:
         (o) event=none
         (x) systemd=suspends again
         (o) acpid=resumes
         (x) state=close
      2. resumed by other:
         (o) event=none
         (x) systemd=suspends again
         (o) acpid=resumes
         (o) state=close
   2. non-cached
      1. resumed by lid:
         (o) event=none
         (x) systemd=suspends again
         (o) acpid=resumes
         (o) state=open
      2. resumed by other:
         (o) event=none
         (x) systemd=suspends again
         (o) acpid=resumes
         (o) state=close

As a conclusion:
 1. With systemd changed, lid_init_state=ignore has only one problem and the
    problem comes from an underlying issue, not userspace and kernel lid
    handling.
 2. Without systemd changed, lid_init_state=open can be the default
    behavior as the pass ratio is not much worse than lid_init_state=ignore.
 3. lid_init_state=method is buggy, we can have a separate patch to make it
    deprectated.
