This adds a device tree for the NanoPC-T4 SBC, which is based on the
Rockchip RK3399 SoC and marketed by FriendlyELEC.

Known working:

- Serial
- Ethernet
- HDMI
- USB 2.0

All of the interesting stuff is in a .dtsi because there are at least
two other boards that share most of it: NanoPi M4 and NanoPi NEO4.

v2: - Rename compatible from friendlyelec to friendlyarm, to match
      existing bindings
    - Remove superfluous node spi1

v3: - Rewrite regulator tree to match the schematics (Heiko)
    - Sort top-level nodes alphabetically (Heiko)
    - Used defines for GPIO numbers (Heiko)
    - Enabled rga (Heiko)
    - Removed cdn_dp node (Heiko)
    - Removed dependencies to fusb0 as extcon (Heiko)
    - Removed superfluous properties (Heiko)
