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)

looks pretty good overall, just some more small-scale things
below.

These are definitly sorted in the Makefile, so this should move between
rk3399-gru-scarlet-kd.dtb and rk3399-puma-haikou.dtb :-)

dt-spec mandates node names with "-", so this should become
	vcc3v0_sd: vcc3v0-sd {

Same for most regulators above.

rename rk808-clkout1 to xin32k so that it hooks correctly into
the rk3399 clock controller, as that signals is providing the 32kHz clock
for the system. (see $debug/clk/clk_summary and rk3399-cru dt binding)

rga is not dependant on pinout, so is always enabled in rk3399.dtsi
So this node can go away.

remnant from the vendor-kernel?
Should also go away.

I still don't think that extcon gets defined at all and is also
not specified in any dwc3 binding, so should probably go away.

keep-power-in-suspend is for SDIO only.
