I think it would be nicer to define a handler under AspeedBoardConfig,
something like :
int (*i2c_init)(AspeedBoardState *bmc);
when a board needs I2C devices. The handler would be called
from aspeed_board_init() directly. This is similar to what
we do for the flash modules but we didn't have to add a
specific handler for the flash.
Thoughts ?
