xen/device_tree: introduce find_compatible_node
Introduce a find_compatible_node function that can be used by device
drivers to find the node corresponding to their device in the device
tree.
Initialize device_tree_flattened early in start_xen, so that it is
available before setup_mm. Get rid of fdt in the process.
Also add device_tree_node_compatible to device_tree.h, that is currently
missing.
