board: gateworks: venice: add imx8mp-gw72xx-2x support

The Gateworks imx8mp-venice-gw72xx-2x consists of a SOM + baseboard. The GW702x SOM contains the following: - i.MX8M Plus SoC - LPDDR4 memory - eMMC Boot device - Gateworks System Controller (GSC) with integrated EEPROM, button controller, and ADC's - PMIC - SOM connector providing: - eQoS GbE MII - 1x SPI - 2x I2C - 4x UART - 2x USB 3.0 - 1x PCI - 1x SDIO (4-bit 3.3V) - 1x SDIO (4-bit 3.3V/1.8V) - GPIO The GW72xx Baseboard contains the following: - 1x RJ45 GbE (eQoS from SOM) - 1x RJ45 GbE (PCI) - off-board I/O connector with MIPI-CSI (3-lane), MIPI-DSI (4-lane), - off-board I/O connector with RS232/RS485 - off-board I/O connector with SPI - off-board I/O connector with I2C, UART, and GPIO I2C, I2S and GPIO - microSD (1.8V/3.3V) - GPS - Accelerometer - EERPOM - USB 3.0 Hub - Front Panel bi-color LED - re-chargeable battery (for RTC) - PCIe clock generator - PCIe switch - 1x USB Type-A host socket with USB 3.0 support - 1x USB OTG with USB 2.0 support - 1x MiniPCIe socket with PCI and USB 2.0 - 1x MiniPCIe socket with SIM, PCI/USB 3.0 (mux), and USB 2.0 - Wide range DC input supply Signed-off-by: Tim Harvey <[email protected]>
