x86/mm/numa: Open code function early_get_boot_cpu_id()
Previously early_acpi_boot_init() was called in early_get_boot_cpu_id()
to get the 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 anymore, and
only the getting boot-time SMP configuration code was left.
So in this patch we open code it.
Also move the smp_found_config check into default_get_smp_config to
simplify code, because both early_get_smp_config() and get_smp_config()
call x86_init.mpparse.get_smp_config().
Also remove the redundent CONFIG_X86_MPPARSE #ifdef check when we call
early_get_smp_config().
