[POWERPC] Document and implement an improved flash device binding for powerpc
This replaces the binding for flash chips in booting-without-of.txt with an clarified and improved version. It also makes drivers/mtd/maps/physmap_of.c recognize this new binding. Finally it revises the Ebony device tree source to use the new binding as an example.
