Commit 2e60161337 split up
arch/powerpc/boot/of.c so that some OF functions can be used on
platforms that don't want to use the overall OF platform boot code.
This is useful on things like PReP which can have an OF implementation
which is useful for debugging output, but inadequate for booting.
However, that commit didn't export quite enough things to make a
usable OF console on a non-OF system. In particular, the device tree
manipulation performed to initialize the OF console code must
explicitly use the OF device tree, rather than the flattened device
tree, even if the system is otherwise booting using a flattened device
tree. This makes it so.

Fixes the constantness of the powerpc bootwrapper's console_ops.write
routine. Allows printing of constant strings.

Currently, all OF-related code in the bootloader is contained in of.c.
of.c also provides the platform specific things necessary to boot on
an OF platform.
However, there are platforms (such as PReP) which can include an OF
implementation, but are not bootable as pure OF systems. For use by
such platforms, this patch splits out the low-level parts of the OF
code (call_prom() and various wrappers thereof) into a new oflib.c
file. In addition, the code related to bootwrapper console output via
OF are moved to a new ofconsole.c file. Both these files are included
in the wrapper.a library where they can be used by both full-OF and
partial OF platforms.
