[PATCH v2] bcm53xx: add support for Asus RT-AC88U

[Arınç ÜNAL]

Hey Rafał.

How should we proceed with this patch?

We can just ditch the nvram script and get the patch applied if that’s 
what you want. It’s just the wireless LEDs that won’t work along with a 
randomised MAC address of the eth2 interface derived from GMAC2.

However, we could use the script for other devices on the same target. I 
believe other devices on this target (e.g. Linksys EA9500) would benefit 
the specified variables as well.

It would be a nice way of setting some nvram variables for devices on 
this target.

Let me know.
