[iot] Support 1G DDR AIY board

Add 1G DDR support, distinguish different boards by the
Board ID, They are:
  SAI5_MCLK: Board_id[6]
  SAI5_RXFS: Board_id[5]
  SAI5_RXC:  Board_id[4]
  SAI5_RXD3: Board_id[3]
  SAI5_RXD2: Board_id[2]
  SAI5_RXD1: Board_id[1]
  SAI5_RXD0: Board_id[0]
Current Board ID for imx8m boards are:
  AIY  Micron  1G:   0x5c
  AIY  Hynix   1G:   0x56
  AIY  Mirconb 3G:   0x40
  Wibo         3G:   0x00
  imx8m_ref    3G:   0x00

Test: Boot ok on all imx8m boards.
