There's no logic to numerically order the CPU ports. State the port number
and its being a CPU port instead.
Remove the irrelevant PHY muxing information from
mt7530_mac_port_get_caps(). Explain the supported MII modes instead.
Remove the out of place PHY muxing information from
mt753x_phylink_mac_config(). The function is for both the MT7530 and MT7531
switches but there's no phy muxing on MT7531.
Fixes: ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK API")
Fixes: 38f790a80560 ("net: dsa: mt7530: Add support for port 5")
Fixes: 88bdef8be9f6 ("net: dsa: mt7530: Extend device data ready for adding a new hardware")
Fixes: c288575f7810 ("net: dsa: mt7530: Add the support of MT7531 switch")
