[PATCH] powerpc: declare arch syscalls in <asm/syscalls.h>

Browse Source 
powerpc currently declares some of its own system calls
in <asm/unistd.h>, but not all of them. That place also
contains remainders of the now almost unused kernel syscall
hack.

 - Add a new <asm/syscalls.h> with clean declarations
 - Include that file from every source that implements one
   of these
 - Get rid of old declarations in <asm/unistd.h>

This patch is required as a base for implementing system
calls from an SPU, but also makes sense as a general
cleanup.
