board_early_init_f is too early to call i2c related setting, because init_func_i2c is called after board_early_init_f being invoked. Thus move setup_i2c into board_init.
Also PFUZ is connected to I2C bus 0, so change "1" -> "0".
Using this patch PFUZ can be correctly probed: "PMIC: PFUZE100 ID=0x11"
