ARM: zynq: Convert Syzygy to DM_I2C

Browse Source 
Boards have only one controller enabled that's why move to DM_I2C is
easy.
Add also i2c alias for not to be shown as i2c bus -1 because alias
doesn't exist.
Config file points to MAC stored in eeprom but it is not listed that's
why I have added 24c08 part.
