David Gibson 3af82a8b00 [POWERPC] Clean up zImage handling of the command line
This cleans up how the zImage code manipulates the kernel
command line.  Notable improvements from the old handling:
	- Command line manipulation is consolidated into a new
prep_cmdline() function, rather than being scattered across start()
and some helper functions
	- Less stack space use: we use just a single global command
line buffer, which can be initialized by an external tool as before,
we no longer need another command line sized buffer on the stack.
	- Easier to support platforms whose firmware passes a
commandline, but not a device tree.  Platform code can now point new
loader_info fields to the firmware's command line, rather than having
to do early manipulation of the /chosen bootargs property which may
then be rewritten again by the core.

To extract the kernel vmlinux, System.map, .config or initrd from the zImage binary:

objcopy -j .kernel:vmlinux -O binary zImage vmlinux.gz
objcopy -j .kernel:System.map -O binary zImage System.map.gz
objcopy -j .kernel:.config -O binary zImage config.gz
objcopy -j .kernel:initrd -O binary zImage.initrd initrd.gz
