Dynamically generate a unique GPIO interrupt name, based on the
device name and the GPIO name. For example:
103: 0 sx1503q 12 Edge sff2-los
104: 0 sx1503q 13 Edge sff2-tx-fault
The sffX indicates the SFP the los and tx-fault are associated with.

v2:
- added net-next to PATCH part of subject line
- switched to devm_kasprintf()
