OpenWrt 21.02 only uses ath79, ar71xx has been dropped. However,
in ath79 the TP-Link CPE210 v1 and CPE510 v1 are implemented as
two-port devices. We currently do not support that in our firmware.
Thus, disable both devices by commenting out their image selectors.
Note that this will still build them, and only prevent having the
images in our dedicated folder.
If support is reestablished, this patch simply needs to be
reverted.
