Add support to listen HW safety IRQ like ECC(error
correction code), DPP(data path parity), FSM(finite state
machine) fault in common IRQ line.

As I see .safety_feat_irq_status available not just in dwmac5 but 
in dwxgmac2_core and that means that the subject line is not just about dwmac5

Right. Suraj, could you please fix the subject to be describing the
actual change? The commit message body more-or-less describes it
correctly.

Well, I guess this is the best we can do with no IRQs handling part
refactoring.

s/IRQ safety IRQ/IRQ sfty
* Although I would have also converted this to just dev_dbg() since
* the IRQ line is optional and is present on a single platform you
* have.


With the subject and the log-message fixed feel free to add:
