net: dsa: b53: Add ability to enable/disable port interrupts

Some switches expose individual interrupt line(s) for port specific
event(s), allow configuring these interrupts at an appropriate time
during port_enable/disable callbacks where all port specific resources
are known to be set-up and ready for use.
