[PATCH 2/2] powerpc: move sync_file_range2 compat definition

sync_file_range2 is not a special unaligned-odd-pair calling convention
syscall, it's just a regular one that does not have a generic compat
definition. Move it out of sys_ppc32.c and into syscalls.c.

This one doesn't fix anything and is not required for the previous
fix, so it could be merged later. Now that we've repurposed sys_ppc32.c
for the difficult syscalls and compat syscalls live all over the kernel
now anyway, IMO it's makes things less confusing to move this.
Thanks,
Nick
