Nicholas Piggin 555e28179d powerpc/64: remove support for kernel-mode syscalls ...

There is support for the kernel to execute the 'sc 0' instruction and
make a system call to itself. This is a relic that is unused in the
tree, therefore untested. It's also highly questionable for modules to
be doing this.
