Make the mpc85xx platform a kobj base class.

Browse Source 
Summary:
Some systems are based around mpc85xx, but need special initialization.  By
making the mpc85xx platform a base class, these systems can be platform
subclasses, and perform board-specific initialization in addition to the mpc85xx
initialization.

Test Plan:
Tested on my RB800.  A platform class was created, and will be committed
separately.
