net: dsa: lantiq_gswip: support model-specific mac_select_pcs() 



Call mac_select_pcs() function if provided in struct gswip_hwinfo.
The MaxLinear GSW1xx series got one port wired to a SerDes PCS and
PHY which can do 1000Base-X, 2500Base-X and SGMII. Support for the
SerDes port will be provided using phylink_pcs, so provide a
convenient way for mac_select_pcs() to differ based on the hardware
model.
