There is no interrupt storm. XGMAC_TSIE was never enabled before this
patch (XGMAC_INT_DEFAULT_EN was LPIIE | PMTIE only), and
dwxgmac2_host_irq_status() masks the status with the enable mask, so
XGMAC_INT_TSIS could never fire. The actual symptom is that
auxiliary-snapshot extts events were never reported -- a feature that
was never wired up, not a live interrupt storm.

So I'd like to keep this on net-next as a new feature rather than
retarget it to net.

Thanks,
Zxyan
