Codrin Ciubotariu 27b5756954 net/fm: Enable FMAN ports if l2switch ports are connected over SGMII
If SerDes is configured to connect L2 Switch ports from T1040
over SGMII or QSGMII, the two FMAN fixed ports (FM1@DTSEC1 and FM2@DTSEC2)
that are connected to two L2 swtch ports must be enabled. These
ports don't have PHYs and must be treated accordingly.
