[PATCH v2] arm64: dts: add support for SolidRun Clearfog GT 8K

[baruch@tkos.co.il (Baruch Siach)]

The SolidRun Clearfog GT-8K is based on Marvell Armada 8040 SoC.

  https://wiki.solid-run.com/doku.php?id=products:a8040:clearfoggt8k

The following devices were tested with this DT on top of kernel
v4.19-rc1:

  * 1GB Ethernet WAN

  * 4 ports 1GB Ethernet switch (2.5GB uplink)

  * SATA on CON3 PCIe slot

  * USB3 type A port

  * SD card and eMMC

  * 2 LEDs

  * 2 push buttons

Signed-off-by: Baruch Siach <baruch@tkos.co.il>
---
v2:
  * Add SATA node

  * Set front button code to KEY_WPS_BUTTON

  * Use LEDs labels more aligned to conversion

  * Document the marvell,reg-init meaning
