  J784S4 EVM board is designed for TI J784S4 SoC. It supports the following
interfaces:
* 32 GB DDR4 RAM
* x2 Gigabit Ethernet interfaces capable of working in Switch and MAC mode
* x1 Input Audio Jack, x1 Output Audio Jack
* x1 USB2.0 Hub with two Type A host and x1 USB 3.1 Type-C Port
* x2 4L PCIe connector
* x1 UHS-1 capable micro-SD card slot
* 512 Mbit OSPI flash, 1 Gbit Octal NAND flash, 512 Mbit QSPI flash,
  UFS flash.
* x6 UART through UART-USB bridge
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs
* 40-pin User Expansion Connector
* x2 ENET Expansion Connector, x1 GESI expander, x2 Display connector
* x1 15-pin CSI header
* x6 MCAN instances

Add basic support for J784S4-EVM.
