powerpc: Implement smp_release_cpus() in C not asm
There's no reason for smp_release_cpus() to be asm, and most people can make more sense of C code. Add an extern declaration to smp.h and remove the custom one in machine_kexec.c Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
