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.
