[patch 1/3] PS3: Fix CONFIG_SMP=n, CONFIG_KEXEC=y build

[geoffrey.levand]

From: Jeremy Kerr <jk@ozlabs.org>

Currently, the ps3 kernel fails to build without smp but with kexec, as
ps3_kexec_cpu_down needs ps3_smp_cleanup_cpu, which isn't defined on UP
kernels. This change adds an empty ps3_smp_cleanup_cpu for UP kernels.

Booted on ps3.
