net: stmmac: dwmac4: fix PCS duplex mode decode
dwmac4 was decoding the duplex mode from the GMAC_PHYIF_CONTROL_STATUS register incorrectly, using GMAC_PHYIF_CTRLSTATUS_LNKMOD_MASK (value 1) rather than GMAC_PHYIF_CTRLSTATUS_LNKMOD (bit 16). Fix this. Fixes: 70523e639bf8c ("drivers: net: stmmac: reworking the PCS code.")
