net: stmmac: Call xpcs_config_eee_mult_fact() only when xpcs is present
Some dwmac variants such as dwmac_socfpga don't use xpcs but lynx_pcs.
Don't call xpcs_config_eee_mult_fact() in this case, as this causes a
crash at init :
Unable to handle kernel NULL pointer dereference at virtual address 00000039 when write
[...]
Call trace:
xpcs_config_eee_mult_fact from stmmac_pcs_setup+0x40/0x10c
stmmac_pcs_setup from stmmac_dvr_probe+0xc0c/0x1244
stmmac_dvr_probe from socfpga_dwmac_probe+0x130/0x1bc
socfpga_dwmac_probe from platform_probe+0x5c/0xb0
