This commit assigns class-flags to devices. The following scheme is
used:

 - ath9k & ath10k: tiny if RAM <128M
 - ath10k & ath10k: tiny if RAM <256M
 - all: tiny if RAM <64M
 - all: tiny if flash <8M

All other devices automatically have the default device-class selected.

The Aruba Instant On AP11 is the Aruba AP-303 with a stripped-down
firmware. Add an alias for the device to remove confusion about the
different naming.

Remove the ath10k-ct-smallbuffers variant from the default
package-seleciton as it clashes with the QCA ath10k driver.

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

This changes the ath10k firmware and driver selection, as
ath10k-ct is now the default in upstream OpenWrt.

However, for 802.11s operation we need the QCA firmware and driver.

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

This device is a dual 5GHz device. It is recommended to manually change the
radio of the first device to the lower 5GHz channels and the second radio
to the upper 5GHz channels.

Add support for IBSS meshing. Leave target marked as BROKEN for IBSS
as stability is unknown and WiFi LEDs are not working.

Functionality was tested in the network of Freifunk Frankfurt with other
ipq40xx and ar71xx devices.

This commit adds support for the new ipq40xx target.
