of/flattree: Make unflatten_device_tree() safe to call from any arch
This patch makes unflatten_device_tree() safe to call from any arch
setup code with the following changes:
- Make sure initial_boot_params actually points to a device tree blob
before unflattening
- Make sure the initial_boot_params->magic field is correct
- If CONFIG_OF_FLATTREE is not set, then make unflatten_device_tree()
an empty static inline function.
This patch also adds some additional debug output to the top of
unflatten_device_tree().
