It is set to 0x1F by default and can be overwritten on the board header file by defining CONFIG_UTBIPAR_INIT_TBIPA. This allows the CPU to simply "reserve" one SMI address instead of using a different one for each UEC.

Fixed a misunderstanding in the original implementation, 'devnum' that was used in the cpu/ppc4xx/4xx_enet.c implementation was NOT the PHY's SMI address, rather it was the number of the MAC interface on the CPU. The equivalent of this for uec_phy will be the UEC number stored in mii_info->dev->name. Usage example is updated for uec.
