Update the M2 socket gpio hogs such that they are not active on boot by
flagging them as GPIO_ACTIVE_HIGH so that 'output-high' drives high.

Update the UART config gpio hogs such that it is configured for RS232
by default on boot. Additionally rename them to match the names used
on the reset of the venice boards.

The upstream Linux DSA drivers do not require phy-handle nodes in
the DSA ports yet the U-Boot DSA drivers do. Add a phy-handle and
the mdio nodes to the u-boot.dtsi file so that future dts file
syncrhonization between Linux and U-Boot don't break networking.

The GW74xx is based on the i.MX 8M Plus SoC featuring:
- LPDDR4 DRAM
- eMMC FLASH
- Gateworks System Controller
- PCIe Gen 3.0 switch (build option)
- USB 3.0 HUB
- USB Type-C front panel connector
- GPS
- 3-axis accelerometer
- CAN bus
- 6x GbE RJ45 front-panel jacks
- 1x IMX8M FEC RGMII GbE (with Passive PoE)
- 5x IMX8M EQOS RGMII 6 port GbE Switch
(1x with 802.3af class 5 Active PoE)
- RS232/RS485/RS422 serial transceiver
- MIPI header (DSI/CSI/GPIO/PWM/I2S)
- DigI/O header (UART/GPIO/I2C/ADC)
- 802.11ac WiFi
- Bluetooth BLE
- 3x MiniPCIe sockets with PCI/USB
- 1x M.2 Socket with USB2.0, PCIe, and dual-SIM
- PMIC
- Wide range DC input supply (8V to 60V DC)
Do the following to add support for this and future imx8mp-venice boards:
- add dts
- add DRAM config
- add PMIC config
- add IMX8MP support in spl.c and venice.c
