====================
net: phylink: remove pcs_poll

This small series removes the now unused pcs_poll members from DSA and
phylink. "git grep pcs_poll drivers/net/ net/" on net-next confirms that
the only places that reference this are in DSA core code and phylink
code:

drivers/net/phy/phylink.c:              if (pl->config->pcs_poll || pcs->poll)
drivers/net/phy/phylink.c:              poll |= pl->config->pcs_poll;
net/dsa/port.c: dp->pl_config.pcs_poll = ds->pcs_poll;
