Kill off addRamDisk (David Gibson)

[ppc-dev at storix.com]

Just a thought on removing addRamDisk

I know that addRamDisk was designed for iseries, but there were some uses with 
pSeries. Right now I use proceedures similar to the makefile for creating 
zImage.initrd images for network boot. This is a clunky process and I would 
rather use yaboot but cannot due to kernel size limitations. (another story). 
If you remove it, we should make sure there are still efficient and practical 
ways for users of 32-bit and 64-bit systems to create zImage.initrd images. 
Otherwise, it seems harmless to remove.
