i2c-eg20t: use i2c_add_numbered_adapter to get a fixed bus number
Feng Tang [Thu, 12 Jan 2012 07:38:02 +0000 (15:38 +0800)]
For EG20T and ML7213 IOH, the i2c controller numbers are fixed, using
fixed bus number will make it much easier for platform code to use
i2c_register_board_info() to register i2c devices.
