has an IMX8MN UltraLite SoC and DDR3L memory. It esp. differs in the
PMIC configuration because the SoC has a smaller package and thus the
ARM core voltage is combined with the SoC voltage and the DDR voltage

This patch adds the device tree to support Toradex Verdin iMX8M Plus [1]
a computer on module which can be used on different carrier boards.

The module consists of an NXP i.MX 8M Plus family SoC (either i.MX 8M
Plus Quad or 8M Plus QuadLite), a PCA9450C PMIC, a Gigabit Ethernet PHY,
1, 2, 4 or 8 GB of LPDDR4 RAM, an eMMC, a TLA2024 ADC, an I2C EEPROM, an
RX8130 RTC, an optional I2C temperature sensor plus an optional
Bluetooth/Wi-Fi module.

Anything that is not self-contained on the module is disabled by
default.

The device tree for the Dahlia includes the module's device tree and
enables the supported peripherals of the carrier board.

The device tree for the Verdin Development Board includes the module's
device tree as well as the Dahlia one as it is a superset and supports
almost all peripherals available.

So far there is no display functionality supported at all but basic
console UART, USB host, eMMC and Ethernet functionality work fine.

At the moment, the dtsi will force the dr_mode to host. This is
problematic because it will always turn on the Vbus voltage regardless
if the port is host or device. This might lead to a "shortcut" between
the two USB endpoints because both might have their Vbus supplies
enabled. Therefore, the default should be "otg" for any ports which
aren't host only (from a SoC point of view) and have a user of the dtsi
file overwrite that explicitly.

Move the 'dr_mode = "host";' into the board dts. Now that the dtsi
doesn't set the dr_mode anymore, we can also drop the 'dr_mode = "otg";'
in the board dts because that is the default value if dr_mode is not
set.
