[RFC 36/52] i386: Use init_apicid_topo_info() to initialize APIC ID topology for system emulator

[Zhao Liu <zhao1.liu@linux.intel.com>]

From: Zhao Liu <zhao1.liu@intel.com>

Since APIC ID for hybrid CPU topology needs to consider maximum possible
structures for each topology levels, the APIC IDs for hybrid CPU topology
and smp CPU topology may be different.

User emulator doesn't support hybrid CPU topology so use
init_apicid_topo_info() for system emulator.
