Subject: [PATCH net-next 1/2] net: dsa: remove pcs_poll

With drivers converted over to using phylink PCS, there is no need for
the struct dsa_switch member "pcs_poll" to exist anymore - there is a
flag in the struct phylink_pcs which indicates whether this PCS needs
to be polled which supersedes this.
