For imx7, "int0" is the interrupt for queue 0 and ENET_MII
"int1" is for queue 1
"int2" is for queue 2
For imx6sx, "int0" handles all 3 queues and ENET_MII
And of course, the "pps" interrupt is for the PTP_CLOCK_PPS interrupts
This will help document what each interrupt does.

v2: replaced empty names with "int0","int1", or "int2"
reordered imx7 interrupts so that "int0", for queue 0, is first.
v3: renamed "ptp" interrupt to "pps", added binding documentation
for interrupt-names.
v4: add blank, ie s/"int0","pps"/"int0", "pps"/ as suggested by Andrew Lunn
