do not yet support SerDes interfaces, that leaves us with just

Extract the logic from b53_adjust_link() responsible for overriding a
given port's link, speed, duplex and pause settings and make two helper
functions to set the port's configuration and the port's link settings.
We will make use of both, as separate functions while adding PHYLINK
support next.

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.
