board: gateworks: venice: add imx8mn-gw7902 support
The GW7902 is based on the i.MX 8M Mini / Nano SoC featuring:
- LPDDR4 DRAM
- eMMC FLASH
- Gateworks System Controller
- LTE CAT M1 modem
- USB 2.0 HUB
- M.2 Socket with USB2.0, PCIe, and dual-SIM
- IMX8M FEC
- PCIe based GbE
- RS232/RS485/RS422 serial transceiver
- GPS
- CAN bus
- WiFi / Bluetooth
- MIPI header (DSI/CSI/GPIO/PWM/I2S)
- PMIC
To add support for the i.MX8M Nano GW7902:
- Add imx8mn-venice dts/defconfig/include
- Add imx8mn-gw7902 dts
- Add imx8mn-2gb lpddr4 dram configs
- Add misc support for IMX8M Nano SoC
- rename imx8mm-venice.c to venice.c as it is no longer imx8mm specific
- update README with differences for IMX8MN vs IMX8MM
