IPQ806X support dropped from mainline

[Tim Small]

Apologies if all the relevant people are already aware, but just in case 
- according to a Phoronix article...

"[In upstream Linux 7.1] the Qualcomm APQ8084 and IPQ806X SoCs are now 
removed as they had only very basic support and no actual supported 
products by the mainline Linux kernel using them."

Looking at the wiki page, this seems to impact quite a few currently 
supported devices.

Upstream or perish I suppose!

Hope this is useful info for someone.

Tim.
