Public bug reported:
[Impact]
For interrupt controller that doesn't support irq_disable and hardware
with level interrupt, an extra interrupt may be pending. This patch fixes
the issue by setting IRQ_DISABLE_UNLAZY flag for the interrupt line,
as suggested by,
'commit e9849777d0e2 ("genirq: Add flag to force mask in
disable_irq[_nosync]()")'
[Test Case]
Run iperf on a merlin board to exercise the xgene_enet driver
[Regression Risk]
This commit only affects the xgene_enet driver
