x86: Replace apic->apicid_to_node() with ->x86_32_numa_cpu_node()

apic->apicid_to_node() is 32bit specific apic operation which
determines NUMA node for a CPU.  Depending on the APIC
implementation, it can be easier to determine NUMA node from
either physical or logical apicid.  Currently,
->apicid_to_node() takes @logical_apicid and calls
hard_smp_processor_id() if the physical apicid is needed.

This prevents NUMA mapping from being queried from a different
CPU, which in turn makes it impossible to initialize NUMA
mapping before SMP bringup.

This patch replaces apic->apicid_to_node() with
->x86_32_numa_cpu_node() which takes @cpu, from which both
logical and physical apicids can easily be determined.  While at
it, drop duplicate implementations from bigsmp_32 and summit_32,
and use the default one.
