ACPI video: support _BQC/_BCL/_BCM methods that use index values
The input/output of _BQC/_BCL/_BCM control methods should be represented
by a number between 0 and 100, and can be thought of as a percentage.
But some buggy _BQC/_BCL/_BCM methods use the index values instead.

Add the functionality to support such kind of BIOSes in ACPI video driver.
