Add a basic dts for the Microchip Smart Embedded Vision dev kit.
The SEV kit is an upcoming first party board, featuring an MPFS250T and:
- Dual Sony Camera Sensors (IMX334)
- IEEE 802.11 b/g/n 20MHz (1x1) Wi-Fi
- Bluetooth 5 Low Energy
- 4 GB DDR4 x64
- 2 GB LPDDR4 x32
- 1 GB SPI Flash
- 8 GB eMMC flash & SD card slot (multiplexed)
- HDMI2.0 Video Input/Output
- MIPI DSI Output
- MIPI CSI-2 Input
