Fixes #1084

Hardware is very similar to Archer C5v1 and C7v2.

Tested factory install and autoupdater.

IBSS Mesh on 2.4 and 5 GHz is working fine.

The only Ethernet Port is used for config mode and afterwards handled
as WAN Port.

Completely untested for now.

Closes #835

The TL-WR940N doesn't have detachable antennas. Make v1-v3 match v4.

Switch sha512sum to sha256sum to match updated autoupdater.

The size of the factory images is limited to 4MB, which caused build
failures when many additional packages were included.

Rather than moving the device to ar71xx-tiny, we ignore the factory images
and just build the sysupgrade. This way, the whole flash is usable for
Gluon.

This means that installing Gluon on these devices will now require to flash
a plain LEDE image first, and then upgrading using the Gluon sysupgrade
image.

Fixes #1020

To fix the autoupdater.

Remove obsolete x86-xen_domu definition, it has been merged into
x86-generic.

Fixes #1022

These devices don't have unique MAC addresses with OpenWrt/LEDE at the moment
(see #993).

The GLUON_ATH10K_MESH must be set to 11s or ibss; when it is not set,
ath10k device images won't be built at all. This also allows us to remove
the BROKEN flag for ath10k devices, as the GLUON_ATH10K_MESH variable is
sufficient to avoid ath10k devices if desired.

Fixes #864

The MR1750 and OM5P-AC devices are based on ath9k SoCs and an external
ath10k chip. All devices which are using ath10k should be marked as broken
due to deficits in their IBSS support.

+ added profile for these devices
+ added entry in the docs for these devices plus the missing alfa tube

Generate flashable images for the Archer C7 v2 with current stock firmware
again.

To set the region code, the GLUON_REGION variable must be set to "us" or
"eu" in site.mk or as a make argument.

Fixes #860

Fixes #800

This patchset enables the RX LNA for the CPE210/510, improving RX by about
20dB. The profiles for CPE210 and CPE510 is split into two images.

The problematic patch switching the CPE510 to the secondary ART is left
out.
