Subject: [RFC PATCH v2 net-next 10/15] net: phylink: support all ethtool port modes with inband modes

Currently, phylink_parse_mode() filters out all port modes except
ETHTOOL_LINK_MODE_MII_BIT for in-band link modes. But if we're going to
accept backplane port modes with inband autoneg, then we should also
allow ETHTOOL_LINK_MODE_Backplane_BIT.

Use phylink_set_port_modes() to just allow them all, and let the
validate() functions of the MAC and phylink_pcs restrict what they don't
support.
