It was being used to set up the core clock and port 6 of the MT7530 switch, and pll of the MT7531 switch. All of these were moved to more appropriate locations, and it was never used for the switch on the MT7988 SoC. Therefore, this function pointer hasn't got a use anymore. Remove it.

The frequency should be checked when the switch is being set up so the driver can reject the unsupported hardware earlier and without requiring port 6 to be used. Move it to mt7530_setup(). Drop the unnecessary function printing.

Phylink deals with the unsupported interface cases before mt7530_setup_port6() is run. Therefore, the default case would never run. However, it must be defined nonetheless to handle all the remaining enumeration values, the phy-modes. Switch to if statement for RGMII and return which simplifies the code and saves an indent. Set P6_INTF_MODE, which is the the three least significant bits of the MT7530_P6ECR register, to 0 for RGMII even though it will already be 0 after reset. This is to keep supporting dynamic reconfiguration of the port in the case the interface changes from TRGMII to RGMII. Disable the TRGMII clocks for all cases. They will be enabled if TRGMII is being used. Read XTAL after checking for RGMII as it's only needed for the TRGMII interface mode. Change mt7530_setup_port6() to void now that there're no error cases left.

The "config" pointer points to &dp->phylink_config, and "dp" is allocated by dsa_port_touch() with kzalloc(), so all its fields are filled with zeroes. There's no code that would change the bitmap beforehand. Remove it.
