PATCH v2 1/1 ARM: dts: BCM5301X: Add support for Linksys EA9500

Hardware Info
-------------

Processor - Broadcom BCM4709C0KFEBG dual-core @ 1.4 GHz
Switch - BCM53012 in BCM4709C0KFEBG & external BCM53125
DDR3 RAM - 256 MB
Flash - 128 MB (Toshiba TC58BVG0S3HTA00)
2.4GHz - BCM4366 4?4 2.4/5G single chip 802.11ac SoC
Power Amp - Skyworks SE2623L 2.4 GHz power amp (x4)
5GHz x 2 - BCM4366 4?4 2.4/5G single chip 802.11ac SoC
Power Amp - PLX Technology PEX8603 3-lane, 3-port PCIe switch
Ports - 8 Ports, 1 WAN Ports
Antennas - 8 Antennas
Serial Port - @J6 [GND,TX,RX] (VCC NC) 115200 8n1

Tested with DSA driver and Kernel 4.14

Note:

"make sure that port 0 of the internal switch is not accidentally configured back to untagged since that would cause problem when terminating the VLAN tag on the SW side." - Florian Fainelli [1]

So, I had to run following bridge command:

bridge vlan add vid 1 dev extsw pvid tagged

Changes in v2:
- Properly define mdio mux, internal mdio, external mdio, mii bus
- Now we define usb3 phy as a mdio node connected to internal mdio Thanks to work done by Rafa? Mi?ecki on the usb3 phy mdio driver
- Define external SW as a mdio-mii node connected to external mdio

PATCH v3 1/1 ARM: dts: BCM5301X: Add support for Linksys EA9500

Hardware Info

Tested with OpenWrt built with DSA driver and Kernel v4.14

Changes in v3:
- Remove unnecessary change to BCH settings
- Remove ports 5 & 7 from internal switch for now
Changes in v2:
- Properly define mdio mux, internal mdio, external mdio, mii bus
- Now we define usb3 phy as a mdio node connected to internal mdio, thanks to work done by Rafa? Mi?ecki on the bcm usb3 phy mdio driver
- Define external SW as a mdio-mii node connected to external mdio
