[PATCH 5/6] board: gateworks: venice: add imx8mm-gw7905-0x support

The Gateworks imx8mm-venice-gw7905-0x consists of a SOM + baseboard.

The GW700x SOM contains the following: - i.MX8M Mini SoC - LPDDR4 memory - eMMC Boot device - Gateworks System Controller (GSC) with integrated EEPROM, button controller, and ADC's - RGMII PHY - PMIC - SOM connector providing: - FEC GbE MII - 1x SPI - 2x I2C - 4x UART - 2x USB 2.0 - 1x PCI - 1x SDIO (4-bit 3.3V) - 1x SDIO (4-bit 3.3V/1.8V) - GPIO

The GW7905 Baseboard contains the following: - GPS - microSD - off-board I/O connector with I2C, SPI, GPIO - EERPOM - PCIe clock generator - 1x full-length miniPCIe socket with PCI/USB3 (via mux) and USB2.0 - 1x half-length miniPCIe socket with USB2.0 and USB3.0 - USB 3.0 HUB - USB Type-C with USB PD Sink capability and peripheral support - USB Type-C with USB 3.0 host support
