[PATCH 2/7] ARM: <asm/io.h>: define macros for I/O memcpy/memset

<asm-generic/io.h> expects architectures to define memcpy_toio,
memcpy_fromio and memset_io as macros as it checks for their existence
with #ifndef. Only ARM defines an own implementation, but does so
as function declaration. Add the missing macros.
