dm: core: Add functions to obtain node's address/size cells
The of_n_addr_cells() and of_n_size_cells() functions are useful for
getting the size of addresses in a node, but in a few places U-Boot needs
to obtain the actual property value for a node without walking up the
stack. Add functions for this and just the existing code to use it.
Add a comment to the existing ofnode functions which do not do the right
thing with a flat tree.
This fixes a problem reading PCI addresses.
