Previously early_acpi_boot_init is called in early_get_boot_cpu_id()
to get value for boot_cpu_physical_apicid. Now early_acpi_boot_init()
has been taken out and moved to setup_arch(), the name of
early_get_boot_cpu_id doesn't match its implementation. And only the
getting boot-time SMP configuration code is left. So in this patch
open code it.
