compile fix for via-pmu-backlight

[Dave Jones <davej@redhat.com>]

Not sure if this is right. I just copied the other conversions.
Given every other driver added a 'NULL' too, I'm a bit suspicious
but I lack the hardware to test this.

drivers/macintosh/via-pmu-backlight.c: In function 'pmu_backlight_init':
drivers/macintosh/via-pmu-backlight.c:150: error: too few arguments to function 'backlight_device_register'
