imx: mx6sabresd: add i.MX6DQP Sabresd support
Add i.MX6DQP-Sabresd board support: 1. set fdt_file according to board_rev which is set at runtime. 2. Add mx6dqp_ddr_ioregs and calibration value for this board. Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Cc: Stefano Babic <sbabic@denx.de> Cc: Fabio Estevam <fabio.estevam@freescale.com>
