[U-Boot] [PATCH 08/42] board: freescale: ls1012aqds: support dm_i2c_* API

[Biwen Li]

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'
