[PATCH net-next v2 0/5] Removing more phylink cruft

["Russell King (Oracle)" <linux@armlinux.org.uk>]

Hi,

Continuing on with the cleanups, this patch series removes
dsa_port_phylink_mac_select_pcs() which is no longer required. This
will have no functional effect as phylink does this:

        bool using_mac_select_pcs = false;

        if (mac_ops->mac_select_pcs &&
            mac_ops->mac_select_pcs(config, PHY_INTERFACE_MODE_NA) !=
              ERR_PTR(-EOPNOTSUPP))
                using_mac_select_pcs = true;

and no mac_select_pcs() method is equivalent to a mac_select_pcs()
that returns -EOPNOTSUPP.

We then make mv88e6xxx_mac_select_pcs() return NULL, as we don't want
to invoke this old behaviour anymore - mv88e6xxx doesn't require it.

Then, allow phylink to remove PCS, which has been a long standing
behavioural oddity.

Remove the use of pl->pcs when validating as this will never be
non-NULL unless "using_mac_select_pcs" was set.

This then clears the way to removing using_mac_select_pcs from phylink
and the check.
