This is a temporary measure that fixes #2692.

This reverts commit 15ef8858.

Use the candelatech firmware for the QCA Wave-2 firmware.

The Qualcomm firmware used for the IPQ401x chip in OpenWrt in 22.03
is experiencing heavily degraded performance due to excessive
retransmits when using A-MSDU. Disabling VHT modes or switching to the
candelatech firmware circumvents this issue.

Apply the same to other Wave-2 platforms in order to keep consistency
with upstream.

Wave-1 chips do not support mesh modes with the -ct firmware, so keep
using the QCA firmware in their case.

This commit removes the broken flag for the ipq806x-generic target,
as the first device (NETGEAR R7800) now has full support in Gluon

This commit accounts for the target renaming which was done in upstream
commit 7407e723991 ("ipqx0xx: add Generic subtarget")

The old bash-based parsing code was way too complex. Replace it with Lua.

The device is broken until the next release. The LEDs are currently not
working (fixed in current OpenWRT master).

Also give a brief explanation about the BROKEN status being dependent on
the WiFi chip used and not the SoC family in general.

as GLUON_WLAN_MESH now is set by default, ATH10K_PACKAGES is set by default, too

defaults to 11s, allowing to build devices without IBSS-support

obsoletes GLUON_ATH10K_MESH

Completely untested for now.

Closes #835
