Adds two more ethernet interface to 83xx 

Added as a convenience for other platforms that uses MPC8360 (has 8 UCC).
Six eth interface is chosen because the platform I am using combines
UCC1&2 and UCC3&4 as 1000 Eth and the other four UCCs as 10/100 Eth.

3090 serves several purposes: 3093 serves several purposes:
3091 3094
3092 - the same features can be used for other OS or standalone 3095 - the same features can be used for other OS or standalone
3093 applications (for instance: using compressed images to reduce the 3096 applications (for instance: using compressed images to reduce the
