This reverts commit e1f550dc44.
platform_get_irq_optional() will still return -ENXIO when no interrupt
is provided so the additional error handling caused the driver prone to
fail when no interrupt was specified. Revert the change so we can apply
the correct minimal fix.

Termination tables change the direction of a packet in hw from RX to SX
pipeline. Use that to offload hairpin flows received from uplink and
sent back to uplink.
Currently termination tables are used for pushing VLAN to packets
received from uplink and targeting a VF. Extend the implementation to
allow forwarding packets to uplink. These packets can either be
encapsulated or not.
In case encapsulation is needed before forwarding, move the reformat
object to the termination table as required.
Extend the hash table key to include tunnel information for the sake of
reusing reformat objects.

Don't use termination tables for packets that are steered to the slow path,
as a pre-step for supporting packet encap (packet reformat) action on
termination tables. Packet encap (reformat action) actions steer the packet
to the slow path until outer arp entries are resolved.

If udevd is configured to rename interfaces according to persistent
naming rules and if a network interface has phys_port_name in sysfs,
its contents will be appended to the interface name.
However, register_netdev creates device in sysfs and if
devlink_port_register is called after that, there is a timeframe in
which udevd may read an empty phys_port_name value. The consequence is
that the interface will lose this suffix and its name will not be
really persistent.
The solution is to register the port before registering a netdev.
