net: dsa: sja1105: fix sja1105_parse_rgmii_delays()

Browse Source 
[ 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.

Fixes: f5b8631c29 ("net: dsa: sja1105: Error out if RGMII delays are requested in DT")
