powerpc: drop MPC8272_ADS platform support
The MPC8272-ADS also supported other 82xx CPU variants, had 64MB RAM, 8MB flash, and like the 85xx ADS platforms, was on a fairly large PCB in order to have space for breakout connectors for all the features. These 82xx platforms are two decades old, and originally made for a small group of industry related people in order to assist in new OEM board designs. Given that, it makes sense to remove support today.
