This supports dm_i2c_* API to
fix compilation error when
enabled CONFIG_DM_I2C as follows:
	- board/freescale/ls1012aqds/built-in.o: In function `misc_init_r:
	  board/freescale/ls1012aqds/ls1012aqds.c:111: undefined reference to
	  `i2c_set_bus_num'
	  board/freescale/ls1012aqds/ls1012aqds.c:113: undefined reference to
	  `i2c_write'
