mpc832x: add support for the mpc8321 based suvd3 board
- serial console on UART1 - Ethernet RMII over UCC4 - PHY SMSC LAN8700 - 64MB Flash - 128 MB DDR2 RAM - I2C - bootcount This board is similiar to the kmeter1 (8360) board, so common config options are extracted into the include/configs/km83xx-common.h file.
