parisc: simplify smp_prepare_boot_cpu()

smp_prepare_boot_cpu() reads the cpuid of the first CPU, printing a
message to state which processor booted, and setting it online and
present.

This cpuid is retrieved from per_cpu(cpu_data, 0).cpuid, which is
initialised in arch/parisc/kernel/processor.c:processor_probe() thusly:

	p = &per_cpu(cpu_data, cpuid);
...
	p->cpuid = cpuid;	/* save CPU id */

Consequently, the cpuid retrieved seems to be guaranteed to also be
zero, meaning that the message printed in this boils down to:

	pr_info("SMP: bootstrap CPU ID is 0\n");

Moreover, since kernel/cpu.c::boot_cpu_init() already sets CPU 0 to
be present and online, there is no need to do this again in
smp_prepare_boot_cpu().

Remove this code, and simplify the printk().
