ath79: migrate Archer C7 5GHz radio device paths

When upgrading a TP-Link Archer C7 v2 from ar71xx to ath79,
the 5ghz radio stops working because the device path changed.

Some people subtitute the unsupported QCA9880v1 in the Archer v1
with supported QCA9880v2 radio. Since the stock radio doesn't
work, so it's safe to apply the change also for the Archer v1
images as well.

Also this patch renames the migration file and variables from
wmac to wifi.
