ACPI: Ignore _BQC object when registering backlight device

According to acpi spec , the objects of  _BCL and _BCM are required if
integrated LCD is present and supports brightness level .The _BQC is
the optional object. So the _BQC object is ignored when the backlight device
is registered in ACPI video driver.
