Andriy Gapon f470cbb2d6 acpi_video: try our best to work on systems without non-essential methods 
Only _BCL and _BCM methods seem to be essential to the driver's
operation.  If _BQC is missing then we can assume that the current
brightness is whatever we set by the last _BCM invocation.  If _DCS or
_DGS is missing the we can make assumptions as well.

The change is based on a patch suggested by Anthony Jenkins
<Scoobi_doo@yahoo.com> in PR 207086.
