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(). Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
