UEC FIXED PHY: Determine fixed-phy port using UEC interface name. 

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.

/*
* Some boards do not have a PHY for each ethernet port. These ports
* are known as Fixed PHY (or PHY-less) ports. For such ports, set
* the appropriate CONFIG_PHY_ADDR equal to CONFIG_FIXED_PHY and
* then define CONFIG_SYS_FIXED_PHY_PORTS to define what the speed and
* duplex should be for these ports in the board configuration
* file.
* Some boards do not have a PHY for each ethernet port. These ports are known
* as Fixed PHY (or PHY-less) ports. For such ports, set the appropriate
* CONFIG_SYS_UECx_PHY_ADDR equal to CONFIG_FIXED_PHY_ADDR (an unused address)
* When the drver tries to identify the PHYs, CONFIG_FIXED_PHY will be returned
* and the driver will search CONFIG_SYS_FIXED_PHY_PORTS to find what network
* speed and duplex should be for the port.
*
* For Example:
* Example board header configuration file:
* #define CONFIG_FIXED_PHY 0xFFFFFFFF
* #define CONFIG_SYS_FIXED_PHY_ADDR 0x1E (pick an unused phy address)
*
* #define CONFIG_PHY_ADDR CONFIG_FIXED_PHY
* #define CONFIG_PHY1_ADDR 1
* #define CONFIG_PHY2_ADDR CONFIG_FIXED_PHY
* #define CONFIG_PHY3_ADDR 3
* #define CONFIG_SYS_UEC1_PHY_ADDR CONFIG_SYS_FIXED_PHY_ADDR
* #define CONFIG_SYS_UEC2_PHY_ADDR 0x02
* #define CONFIG_SYS_UEC3_PHY_ADDR CONFIG_SYS_FIXED_PHY_ADDR
* #define CONFIG_SYS_UEC4_PHY_ADDR 0x04
*
* #define CONFIG_SYS_FIXED_PHY_PORT(devnum,speed,duplex) \
* {devnum, speed, duplex},
* #define CONFIG_SYS_FIXED_PHY_PORT(name,speed,duplex) \
* {name, speed, duplex},
*
* #define CONFIG_SYS_FIXED_PHY_PORTS \
* CONFIG_SYS_FIXED_PHY_PORT(0,SPEED_100,DUPLEX_FULL) \
* CONFIG_SYS_FIXED_PHY_PORT(2,SPEED_100,DUPLEX_HALF)
* CONFIG_SYS_FIXED_PHY_PORT("FSL UEC0",SPEED_100,DUPLEX_FULL) \
* CONFIG_SYS_FIXED_PHY_PORT("FSL UEC2",SPEED_100,DUPLEX_HALF)
