According to commits 2a22b7ae2fa3 ("net: pcs: xpcs: adapt Wangxun NICs
for SGMII mode") and 2deea43f386d ("net: pcs: xpcs: add 1000BASE-X AN
interrupt support"), Wangxun devices need special VR_XS_PCS_DIG_CTRL1
settings for SGMII and 1000BASE-X. Both SGMII and 1000BASE-X use the
same settings.

Rather than placing these in the individual xpcs_config_*() functions,
move it to where we already test for the Wangxun devices in
xpcs_do_config().
