DT currently lists the port mode for the 88E6352 switch 1 to 88E6185
switch 2 as "rgmii-id" but referring to the schematics, it is in fact
a serdes link. The 88E6352 is configured with P5_MODE=6, S_SEL=1 and
S_MODE=1, which means port 5 is configured as 1000BASE-X.
This is confirmed by the value in the 88E6352 port 5 status register,
0x4e09, where C_MODE=9 meaning 1000BASE-X. It is also confirmed by
the 88E6185 port 9 status register, 0x5e8c, where C_MODE=4 meaning
cross-chip SERDES mode is selected.
