spi: fsl_qspi: Fix DDR mode setting for latest iMX platforms On latest iMX platforms like iMX7D/iMX6UL/iMX8MQ, the QSPI controller is updated to have TDH field in FLSHCR register. According to reference manual, this TDH must be set to 1 when DDR_EN is set. Otherwise, the TX DDR delay logic won't be enabled. Another issue in DDR mode is the MCR register will be overwritten in every read/write/erase operation. This causes DDR_EN been cleared while TDH=1, then no clk2x output for TX data shift and all operations will fail. Signed-off-by: Ye Li <ye.li@nxp.com>
