Aaro Koskinen 7cc4fa1e51 staging: octeon-ethernet: rgmii: enable interrupts that we can handle 
Enable only those interrupts that we can handle & acknowledge in the
interrupt handler.

At least on EdgeRouter Lite, the hardware may occasionally interrupt with
some error condition when the physical link status changes frequently.
Since the interrupt condition is not acked properly, this leads to the
following warning and the IRQ gets disabled completely:

[   41.324700] eth0: Link down
[   44.324721] eth0: 1000 Mbps Full duplex, port  0, queue  0
