On iMX7D SabreSD board, the QSPI has pins conflict with EPDC (default). To use QSPI, users have to rework the board (de-populate R388-R391, R396-R399 populate R392-R395, R299, R300). So we add new DTS file and new defconfig dedicated for QSPI.
Other changes to support the DM QSPI:
- Add QSPI node and alias spi0.
- Modify spi4 (spi-gpio) node and add alias spi5 for it to avoid req conflict
- Add EPDC node in imx7d.dtsi and disable it in imx7d-sdb-qspi.dts, to present the conflict.
- Remove iomux settings of qspi in board codes which is not needed for DM driver.

fyi, this will soon remove if no further update on dm- conversion [1]
+CONFIG_FSL_QSPI=y
Better to do full dm conversion before using, otherwise we have migration expire rule [2]
