[PATCH v8 07/14] parisc: Align prototypes of IO memcpy/memset

[Julian Vetter]

Align the prototypes of the memcpy_{from,to}io and memset_io functions
with the new ones from iomap_copy.c and remove function declarations,
because they are now declared in asm-generic/io.h.

Changes for v8:
- Mask the argument with 0xff because now it's an int and not a unsigned
  char anymore
