When booting the QEMU virt machine with -net nic,model=e1000 we can already
support network boot just fine today.

So let's enable the default bootcmd to also evaluate DHCP responses properly.
That way we can enable network boot seamlessly with the virt target.

This commit adds support for the Toradex Colibri iMX7D 1GB Computer
on Module. The module is very similar to the Colibri iMX7D 512MB
but uses eMMC instead of raw NAND. This patch introduces a new
board specific Kconfig symbol to select between the two flash
options.

CONFIG_BOOTDELAY has been migrated to Kconfig, but cl-som-imx7 was
missed. We can just delete the assignments as the config already has
the correct value.

Convert the codes and configurations to enable DM drivers in u-boot for
modules: i2c, PMIC, regulator, USB, Ethernet, SD/MMC, GPIO and QSPI

This patch does not change SPL, so it still uses non-DM driver for
UART, GPIO and SD/MMC.

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.

To support DM QSPI driver
 - Add spi0 and spi1 alias for qspi1 and qspi2.
 - Add -u-boot.dtsi to modify n25q256a@0 and n25q256a@1 compatible string
   to "spi-flash" and add "num-cs" property.
 - Enable DM SPI/QSPI relavent configurations
 - Remove iomux settings of qspi2 in board codes which is not needed
   for DM driver.
 - Add sf default settings. So running "sf probe" can detect the flash

Now that we have full Linux kernel boot support on EFI payload,
avoid pass "acpi=off" to the kernel command line.

This code now is regarded as dead one and hence shall be removed.
