Revert "ACPI: Ignore _BQC object when registering backlight device"

This reverts commit 7c0ea45be4f114d85ee35caeead8e1660699c46f which
caused a regression with the backlight being set to off when a laptop
doesn't have a _BQC entry to query the actual backlight value.  The code
blindly then falls back on a value of 0.
