drivers/intel/gma: Remove _BCL from acpigen

As `INTEL_GMA_ACPI` is selected by default for most Intel SOC's, but if the brightness
control isn't Intels (i.e. `drivers/intel/gma/acpi/default_brightness_levels.asl` isn't
included, there wont be a hook for BCL.

This results in:

```
No Local Variables are initialized for Method [_BCL]
No Arguments are initialized for method [_BCL]
```
