[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.
