A tiny bit more Sansa Fuze v2 work.

- buttonlight works
 - backlight turns on (quite weak though and no brightness adjustment/backlight off functional)
 - don't share drivers with e200v2/fuzev1 for now as it's not entirely clear how dbop plays into this
 - deactivte scrollwheel as it's messing up the timer setup in kernel-as3525.c indicating the dbop input reading doesn't work well
 - still no working bootloader/no lcd or buttons
