ENGR00176834-1 - [imx6] : add fsl_system_rev to check chip and board.
- Add fsl_system_rev to distinguish chip ID and board reversion. - Add some api: mx6_chip_is_dq() mx6_chip_is_dl() mx6_chip_is_solo() mx6_chip_is_sololite() mx6_board_is_reva() mx6_board_is_revb() mx6_board_is_revc() Signed-off-by: Fugang Duan <B38611@freescale.com>
