Chaoyi Chen 2435fca058 arm64: dts: rockchip: Add rk3399-evb-ind board 
General feature for rk3399 industry evaluation board:
- Rockchip RK3399
- 4GB LPDDR4
- emmc5.1
- SDIO3.0 compatible TF card
- 1x HDMI2.0a TX
- 1x HDMI1.4b RX with TC358749XBG HDMI to MIPI CSI2 bridge chip
- 1x type-c DisplayPort
- 3x USB3.0 Host
- 1x USB2.0 Host
- 1x Ethernet / USB3.0 to Ethernet

Tested with HDMI/GPU/USB2.0/USB3.0/TF card/emmc.
