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.

The DTS model name has been changed to "TP-Link Archer C6 v2 (EU/RU/JP)"
to distinguish it from the US version.

Closes #2533

Gone due to
commit 071cf7b2 ("Switch to Lua for target definitions")

Has prior been introduced as untested -> broken in
commit d586720c ("ar71xx-generic: add support for Ubiquiti NanoBeam M5")

Was commented out in the former commit.

Re-add mikrotik target

Note that previous images were generic ones and as such no migration
path is provided other than manually flashing the image via config-mode.

- [x] Must be flashable from vendor firmware
  - [x] Web interface
  - [ ] TFTP (untested, but possible according to OpenWrt wiki)
  - [ ] Other: <specify>
- [x] Must support upgrade mechanism
  - [x] Must have working sysupgrade
    - [x] Must keep/forget configuration (`sysupgrade [-n]`, `firstboot`)
  - [x] Gluon profile name matches autoupdater image name
        (`lua -e 'print(require("platform_info").get_image_name())'`)
- [x] Reset/WPS/... button must return device into config mode
- [x] Primary MAC address should match address on device label (or packaging)
      (https://gluon.readthedocs.io/en/latest/dev/hardware.html#notes)
  - When re-adding a device that was supported by an earlier version of Gluon, a
    factory reset must be performed before checking the primary MAC address, as
    the setting from the old version is not reset otherwise.
- Wired network
  - [x] should support all network ports on the device
  - [x] must have correct port assignment (WAN/LAN)
    - On devices supplied via PoE, there is usually no explicit WAN/LAN labeling on the hardware.
      The PoE input should be the WAN port in this case.
- Wireless network (if applicable)
  - [x] Association with AP must be possible on all radios
  - [x] Association with 802.11s mesh must work on all radios
  - [x] AP+mesh mode must work in parallel on all radios
- LED mapping
  - Power/system LED
    - [x] Lit while the device is on
    - [x] Should display config mode blink sequence
          (https://gluon.readthedocs.io/en/latest/features/configmode.html)
  - Radio LEDs
    - [x] Should map to their respective radio
    - [x] Should show activity
  - Switch port LEDs
    - [x] Should map to their respective port (or switch, if only one led present)
    - [x] Should show link state and activity

Remove a few features that became enabled by default since OpenWrt 19.07.
Disabling CONFIG_RELAY also reduces RAM usage.

Remove kernel symbols which are not required for Gluon.

Gluon still uses firewall3 and iptables, so remove dependency on
nftables.
