powerpc: Initialize secondary CPU setup for 32-bit SMP
32-bit SMP powermacs weren't booting with ARCH=powerpc because the boot cpu wasn't saving away the state of various control registers, but the secondary CPUs were loading them from the uninitialized state. This adds the necessary save-state call. Signed-off-by: Paul Mackerras <paulus@samba.org>
