[U-Boot] [PATCH v2] [83xx] Adds two more ethernet interface to 83xx

[richardretanubun <richardretanubun@ruggedcom.com>]

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

V2 of this patch adds CONFIG_ETH6ADDR to README and removes 
#if defined(CONFIG_HAS_ETH0) from common/cmd_bdinfo.c
