PATCH v5 1/1 wandboard: Add support for the MX6QP variant

From: Fabio Estevam <[email protected]>

Add support for the latest MX6QP wandboard variant.

Based on Richard Hu's work from Technexion's U-Boot tree.

Signed-off-by Fabio Estevam <[email protected]>

Changes since v4:
- Use the existing mx6dq_dram_iocfg() for configuring the DDR IOMUX, still uses a custom spl_dram_init_imx6qp_lpddr3() function because mx6_dram_cfg() does not give stable results.
