Subject: [PATCH v5 01/18] ARM64: Move the init of cpu_logical_map(0) before unflatten_device_tree()

It always make sense to initialize CPU0's logical map entry from the
hardware values, so move the initialization of cpu_logical_map(0)
before unflatten_device_tree() which is needed by ACPI code later.
