[U-Boot-Users] Patch: Support for PQ27e (8247/48/71/72) chips and MPC8272ADS board

Hi,

This patch adds support for the newest additions to Motorola PQII family (MPC8247/8248/8271/8272) known also as PQ27e. They've got different DPRAM layout (as was discussed on the list) so common files were changed. I tested the code on several boards I've got (using both old and new chips). Motorola released new derivative of MPC8260ADS evaluation board supporting these chips: MPC8272ADS. This patch adds support for the new board.
