Adding a Basic DT for the Linksys ea6500 v2 wireless home router

[Renà Kjellerup]

Hi Hauke,

thank you for suggesting adding the dts patch to mainline kernel,
so here it is.
I feel Rafal technically still have the copyrights, this is pretty
much just a few string updates for the ea6500v2. However with this
dts in latest OpenWrt 18.06 loads and installs on my device.

I will be available to do more testing should it be required.

Subject: [PATCH] ARM: dts: BCM5301X: Add basic DT for Linksys EA6500 V2

It's wireless home router based on BCM4708A0 with BCM4360 + BCM4331
wireless chipsets. The BCM4331 5GHz chip currently isn't supported
only due to missing compatible firmware.
