net: ag71xx: phylink validate implementation updates

This series converts ag71xx to fill in the supported_interfaces member
of phylink_config, cleans up the validate() implementation, and then
converts to phylink_generic_validate().

The question over the port linkmode restriction has been answered by
Oleksij - there is no reason for this restriction, so we can go the
whole hog with this conversion. Thanks!
====================

ag71xx apparently only supports MII port type, which makes it different
from other implementations. However, Oleksij says there is no special
reason for this.

Convert the driver to use phylink_generic_validate(), which will allow
all ethtool port linkmodes instead of only MII, giving the driver
consistent behaviour with other drivers.

As phylink checks the interface mode against the supported_interfaces

Add support to inet v4 raw sockets for binding to nonlocal addresses
through the IP_FREEBIND and IP_TRANSPARENT socket options, as well as
the ipv4.ip_nonlocal_bind kernel parameter.

Add helper function to inet_sock.h to check for bind address validity on
the base of the address type and whether nonlocal address are enabled
for the socket via any of the sockopts/sysctl, deduplicating checks in
ipv4/ping.c, ipv4/af_inet.c, ipv6/af_inet6.c (for mapped v4->v6
addresses), and ipv4/raw.c.

Add test cases with IP[V6]_FREEBIND verifying that both v4 and v6 raw
sockets support binding to nonlocal addresses after the change. Add
necessary support for the test cases to nettest.

net: make dev_watchdog() less intrusive

dev_watchdog() is used on many NIC to periodically monitor TX queues
to detect hangs.

Problem is : It stops all queues, then check them, then 'unfreeze' them.

Not only this stops feeding the NIC, it also migrates all qdiscs
to be serviced on the cpu calling netif_tx_unlock(), causing
a potential latency artifact.

With many TX queues, this is becoming more visible.

If the used PHYs also support hardware timestamping, all configuration requests
should be forwared to the PHYs instead of being processed by the MAC driver
itself.

This enables PHY timestamping in combination with the cpsw driver.

Vports' QoS is not commonly used but consume SW/HW resources, which
becomes an issue on BlueField SoC systems.
Don't enable QoS on vports by default on eswitch mode change and enable
when it's going to be used by one of the top level users:
- configuring TC matchall filter with police action;
- setting rate with legacy NDO API;
- calling devlink ops->rate_leaf_*() callbacks.
