fdt: Add fdt_node_offset_by_compat_reg helper
Given a compatible string and physical address try and find a node that matches. This is useful when we want to find a specific device node to update (for example if we have multiple PCI nodes we can use the physical address to distinguish them when trying to update the device tree).
