drivers/intel/gma/acpi: Prevent DivideByZero error
In case backlight control isn't enabled BCLM is zero. Return early instead of running into a DivideByZero error.
This happens on devices that don't have backlight control, like desktops and servers. The proper fix is to not include those ACPI methods, but that requires a much bigger refactoring.
