arm64: dts: imx8mm: add imx8mm-venice-gw72xx-0x-rpidsi overlay for display
Add support for the following Raspberry Pi displays:
- DFROBOT DRF0678 7in 800x480 TFT DSI capacitive touch
- DFROBOT DRF0550 5in 800x480 TFT DSI capacitive touch
Both have the following hardware:
- FocalTech FT5406 10pt touch controller (with no interrupt)
- Powertip PH800480T013-IDF02 compatible panel
- Toshiba TC358762 compatible DSI to DBI bridge
- ATTINY based regulator used for backlight controller and panel enable
Support is added via a device-tree overlay. The touch controller is not
yet supported as polling mode is needed.
