Update the sys_eeprom.c file to handle both NXID and CCID EEPROM formats. The NXID format replaces the older CCID format, but it's important to support both since most boards out there still use the CCID format. This change is in preparation for using one file to handle both formats. This will also unify EEPROM support for all Freescale 85xx and 86xx boards.

Also update the 86xx board header files to use the standard CFG_I2C_EEPROM_ADDR instead of ID_EEPROM_ADDR.

This patch is the first in a series to clean up the MAC address determination in some of Freescale's board. The ultimate goal is to get rid of CONFIG_ETHADDR and related macros in the board header files.
