NUMA enabled kernel on FDT based machine fails to boot because CPUs
are all in NUMA_NO_NODE and mm subsystem won't accept that.
Fix by adding them to default NUMA node at FDT parsing phase and move
numa_add_cpu(0) to a later point.

fdt_check_header(__dtb_start) will always success because kernel
provides a dummy dtb, and by coincidence __dtb_start clashed with
entry of this dummy dtb. The consequence is fdt passed from firmware
will never be taken.
Fix by trying to utilise __dtb_start only when CONFIG_BUILTIN_DTB is
enabled.

Both acpi_table_upgrade() and acpi_boot_table_init() are defined as
empty functions under !CONFIG_ACPI_TABLE_UPGRADE and !CONFIG_ACPI in
include/linux/acpi.h, there are no implicit declaration errors with
various configs.
#ifdef CONFIG_ACPI_TABLE_UPGRADE
void acpi_table_upgrade(void);
#else
static inline void acpi_table_upgrade(void) { }
#endif
#ifdef CONFIG_ACPI
...
void acpi_boot_table_init (void);
...
#else /* !CONFIG_ACPI */
...
static inline void acpi_boot_table_init(void)
{
}
...
#endif /* !CONFIG_ACPI */
As Huacai suggested, CONFIG_ACPI_TABLE_UPGRADE is ugly and not necessary
here, just remove it. At the same time, just keep CONFIG_ACPI to prevent
potential build errors in future, and give a signal to indicate the code
is ACPI-specific. For the same reason, we also put acpi_table_upgrade()
under CONFIG_ACPI.
