ath79: ag71xx: Enable tx hang workaround for the rest of ar724x SoCs

In ar71xx we check for stuck DMA on devices which fall in the is_ar724x
SoC group (ar724x, ar933x, ar934x, qca9533, tp9343, qca955x, qca956x).

In ath79 we're currently performing this check only for devices with
ar7240 SoC, so this patch tries to sync the dma stuck checking behavior
with what is being done in ar71xx.
