[RFC PATCH] Staging: speakup: Added EXPORT_SYMBOL_GPL() markings.

[Tracey Dent]

Changed drivers/char/selection.c so that drivers/staging/speakup/selections.c
could export. Also delete some lines that were unessary since I used
EXPORT_SYMBOL_GPL().

Greg can you review this and tell me if I did it right.
