[PATCH] realtek/rtl839x: Edgecore ECS4100-12PH support

Add support for the Edgecore ECS4100-12PH, an 8-port PoE Gigabit
Ethernet switch with 2 combo RJ45/SFP and 2 SFP ports.

Hardware:
* SoC: RTL8392M
* RAM: 256MiB
* Flash: 32MiB SPI-NOR
* Ethernet:
  * 8x GbE RJ45 PoE (built-in RTL8218B)
  * 2x GbE RJ45 / SFP combo
  * 2x SFP
* Console: RJ45 RS232 port on front panel
* PoE: Nuvoton M0516 + 2x Broadcom BCM59121 PSE

Installation via bootloader:
* open serial console (baud rate 115200)
* interrupt boot process by pressing any key during boot
* boot the OpenWrt initramfs:
  # rtk network on
  # setenv bootcmd 'mtdparts default;sf probe 0;sf read  0x81000000 0x00200000 0x400000;bootm'
  # tftpboot 0x8f000000 /tftpboot/openwrt-realtek-rtl839x-edgecore_ecs4100-12ph-initramfs-kernel.bin
  # bootm
* copy openwrt-realtek-rtl839x-edgecore_ecs4100-12ph-squashfs-sysupgrade.bin
  to /tmp and use sysupgrade to install it:
  # sysupgrade /tmp/openwrt-realtek-rtl839x-edgecore_ecs4100-12ph-squashfs-sysupgrade.bin

I took the DTS from the TIP OpenWiFi project. It was introduced in the
initial commit of their Github repo [1]. I added gpio1 and
label-mac-device, and changed rtl838x-soc in the compatible line to
rtl839x-soc. The info page and photo on svanheule's website suggest
RTL8392M, while my units use RTL8393M. My units have the exact same P/N
and revision on the PCB as in the photo. Since there appear to be units
based on RTL8392M, I'll keep the original DTS filename unless someone
tells me otherwise.

All 4 SFP slots seem to detect SFP insertion and removal, however I
didn't manage to get a link on either of the ports. As I have very
limited experience with SFP/fiber on Linux, I'd appreciate some guidance
on how to test this properly.
