The prototypes for mmioset/mmiocpy are intentionally hidden inside of inline functions, which breaks the EXPORT_SYMBOL statements when symbol versioning is enabled. This adds a prototype to asm/asm-prototypes.h but hides it in an #ifdef so normal drivers don't see it and won't be able to abuse the interface.
