Increase the number of bits in an apicid from 8 to 32.
By default, MP_processor_info() gets the APICID from the
mpc_config_processor structure. However, this structure limits
the size of APICID to 8 bits. This patch allows the caller of
MP_processor_info() to optionally pass a larger APICID that will
be used instead of the one in the mpc_config_processor struct.

When acpi=off or there is no SRAT defined, apicid_to_node is got from K8
Northbridge PCI configuration space in k8_scan_nodes() in
arch/x86_64/mm/k8toplogy.c.
The problem is that it assumes bsp apic id is 0 at that point.
For four socket system with Quad core cpus installed, all cpus apic id
is offset by 4, and bsp apic id is 4.
For eight socket system with dual core cpus installed, all cpus apic id
is offset by 2, and bsp apic id is 2.
We need get boot_cpu_id --- bsp apic id, before k8_scan_nodes by called.
So create early_acpi_boot_init and early_get_smp_config for get boot_cpu_id.
