powerpc_flash_init() implements a broken way of probing for flash
devices supported by the physmap_of driver. It finds all nodes in the
device tree with device_type=="rom" and instantiates of_platform
devices for them. This is fundamentally incompatible with the normal
and correct way of probing for of_platform_bus_probe(). Platforms
which relied on powerpc_flash_init()s behaviour (none are in-tree)
will have to update their platform probing code to correctly probe
busses containing flash devices.

Add missing include in rom.c. Fixes this build error when CONFIG_MTD=y:
arch/powerpc/sysdev/rom.c:26: error: implicit declaration of function

This adds support for flash device descriptions to the OF device tree.
It's inspired by and partially borrowed from Sergei's patch "[RFC]
Adding MTD to device tree.patch".
