staging: ft1000: Remove unnecessary EXPORT_SYMBOLs

 ft1000-pcmcia uses EXPORT_SYMBOL unnecessarily for sharing symbols
 inside the same module. For some reason, this is causing section
 conflicts on ia64 as well, even though neither are static.

 error: __ksymtab_stop_ft1000_card causes a section type conflict
 error: __ksymtab_init_ft1000_card causes a section type conflict
