[ARM] pxa/spitz: use leds-gpio for led driving and drop leds-spitz

Browse Source 
Now as the scoop pins are covered by the generic gpio API,
we can use leds-gpio driver instead of special leds-spitz

Drop leds-spitz.c and the declarations of now un-referenced
spitzscoop_device, spitzscoop2_device.
