imx: imx7d-sdb: Add DM QSPI support 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 align with kernel and also present the conflict. - Add -u-boot.dtsi to modify compatible string of mx25l51245g@0 to "spi-flash" - Remove iomux settings of qspi in board codes which is not needed for DM driver.

dts: switch spi-flash to jedec, spi-nor compatible There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot dts files. This compatible has been added in sf_probe, let use it. This patch switches to jedec,spi-nor when spi-flash is used in the DTS and DTSI files, and removed spi-flash when jedec,spi-nor is already present. The x86 dts are switched in a separate commit since it depends on a change in fdtdec.
