[IA64] /proc/cpuinfo "physical id" field cleanups
Clean up the process for presenting the "physical id" field in
/proc/cpuinfo.
- remove global smp_num_cpucores, as it is mostly useless
- remove check_for_logical_procs(), since we do the same
functionality in identify_siblings()
- reflow logic in identify_siblings(). If an older CPU
does not implement PAL_LOGICAL_TO_PHYSICAL, we may still
be able to get useful information from SAL_PHYSICAL_ID_INFO
- in identify_siblings(), threads/cores are a property of
the CPU, not the platform
- remove useless printk's about multi-core / thread
capability in identify_siblings(), as that information
is readily available in /proc/cpuinfo, and printing for
the BSP only adds little value
- smp_num_siblings is now meaningful if any CPU in the
system supports threads, not just the BSP
- expose "physical id" field, even on CPUs that are not
multi-core / multi-threaded (as long as we have a valid
value). Now we know what sockets Madisons live in too.
