Blackfin: tll6527m: fix spelling in unused code (struct name)

platfrom -> platform

This changes a struct name. The related code is conditionally
compiled and won't work because the include file linux/gpio-decoder.h
is missing, so removing this code would be an even better solution.

If the missing include file is added, it must fix the spelling, too.
