rwsem: Move duplicate function prototypes to linux/rwsem.h
All architecture specific rwsem headers carry the same function
prototypes. Just x86 adds asmregparm, which is an empty define on all
other architectures. S390 has a stale rwsem_downgrade_write()
prototype.
Remove the duplicates and add the prototypes to linux/rwsem.h
