The IOTA2 Lumpy board is based on the i.MX8MPlus EVK.

Basic features are:
- 4GB LPDDR4
- 64GB eMMC
- 2x 1GB Ethernet
- USB 3.0 Type-C dual role port, without power delivery
- USB 3.0 Type-A host port
- RGB LED - PWM driven
- speaker - PWM driven
- RTC with super capacitor backup

v5:
- Moved the gpio and enable-active-high properties below
  the regulatro-* properties in reg_usb_host node.
- Moved the micrel,led-mode properties bellow the reset-*
  properties in ethphy nodes.
- Collected R-b tag from Marco.

v4:
- Moved the iomuxc node to the end of the file.
- Moved the bus-width and non-removeable properties below
  the pinctrl-* properties in &usdhc3 node.
- Moved the fsl,ext-reset-output below the pinctrl-* properties
  in &wdog1 node.
v3:
- Dropped pinctrl-names property from &usb_dwc3_1 node.
v2:
- Dropped unused property from pwm4 node.
- Sorted all nodes and properties using dt-format tool from Frank.
