Global stmmac support for early initialization of PCS devices requires a generic PCS reference that can be passed to phylink_pcs_pre_init(). Currently, the mac_device_info struct contains only one PCS field, which is specific to the Lynx model. As PCS models are hardware-specific, it is more appropriate to have a generic PCS field in the mac_device_info struct. Refactor the lynx_pcs field into a generic phylink_pcs field.
