sh: Split out CPU topology initialization.
Split out the CPU topology initialization to a separate file, and switch it to a percpu type, rather than an NR_CPUS array. At the same time, switch to only registering present CPUs, rather than using the possible CPU map. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
