From: Oleksij Rempel <o.rempel@xxxxxxxxxxxxxx> [ Upstream commit 9bca3a0a923fc3f0fb9e41391be1d0f291e86858 ] This function was using configuration of port 0 in devicetree for all ports. In case CPU port was not 0, the delay settings was ignored. This resulted not working communication between CPU and the switch.
