In order to use the FlexSPI interface in U-Boot, configure
the alias to make spi0 point to flexspi.
With that enabled, sf probe detects the QSPI part as:
SF: Detected n25q256ax1 with page size 256 Bytes, erase size 4 KiB, total 32 MiB

In order to boot over USB, the device tree needs to enable
a few extra nodes in SPL. Since the USB driver has the
ability to detect host/device, the dr_mode can be removed
from the device tree since it needs to act as a device when
booting and OTG is the default mode. Add USB boot support
to spl_board_boot_device and enable the corresponding config
options.

Mark pinctrl_wdog as u-boot,dm-spl to clean up board code,
The set_wdog_reset() function is not necessary as this is handled by
the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property
being set.

With the updated device tree's having USB support, enable in
U-Boot. This also requires the addition of the imx8m power
domain, since the USB is gated by the power domain controller.

Some SD Card controller and power circuitry has increased capacitance,
which keeps the internal logic remains powered after regulator is switch
off. This is generally the case when card is switched to SD104 mode,
where a power cycle should be performed. In case if the card internal
logic remains powered, it causes a subsequent failure of mode
transition, effectively leading to failed enumeration.
Introduce a delay of 20 msec in order to provide a possibility for
internal card circuitry to drain voltages and perform a power cycle
correctly.
Similar fix is done in commit c49d0ac38a ("ARM: dts: rmobile: Increase
off-on delay on the SD Vcc regulator") targeted Renesas SOCs.

Beacon EmbeddedWorks, formerly known as Logic PD, is releasing
a devkit based on the i.MX8M Mini SoC consisting of baseboard +
SOM.
It supports eMMC on the SOM, microSD on the baseboard, various
GPIO, the PINCTRL, and UART.
