sh: Populate initial secondary CPU info from boot_cpu_data.
The secondary CPU info was seeing corrupted results due to not entering all of the setup paths taken by the boot CPU. So we just memcpy() the boot cpu data over directly, and then fix up the per-CPU bits. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
