fdt: introduce fdt_verify_alias_address() and fdt_get_base_address()
Introduce two functions, fdt_verify_alias_address() and fdt_get_base_address(), which can be used to verify the physical address of a device in a device tree. fdt_get_base_address() returns the base address of an SOC or PCI node. fdt_verify_alias_address() prints a message if the address of a node specified by an alias does not match the given physical address.
