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.

Before this patch needs to apply "pci: pcie_imx: Fix hang on mx6qp" from Fabio. http://lists.denx.de/pipermail/u-boot/2015-October/230018.html.
