As a preparatory step remove the epdc reference which does not exist in
the Linux upstream device tree and rename the qspi1 reference to qspi as
this is how it is named in the Linux upstream device tree.
This avoids the following error once synchronised:
+Error: arch/arm/dts/.imx7d-sdb-qspi.dtb.pre.tmp:10.1-6 Label or path
epdc not found
+Error: arch/arm/dts/.imx7d-sdb-qspi.dtb.pre.tmp:29.1-7 Label or path
qspi1 not found
+Error: arch/arm/dts/imx7d-sdb-qspi-u-boot.dtsi:6.1-7 Label or path
qspi1 not found

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.
