net: dsa: b53: Make SRAB driver manage port interrupts
Update the SRAB driver to manage per-port interrupts. Since we cannot sleep during b53_io_ops, schedule a workqueue whenever we get a port specific interrupt. We will later make use of this to call back into PHYLINK when there is e.g: a link state change.
