Subject: [PATCH RFC net-next 09/10] net: pcs: xpcs: drop interface argument
 from xpcs_create*()

The XPCS sub-driver no longer uses the "interface" argument to the
xpcs_create_mdiodev() and xpcs_create_fwnode() functions. Remove
this now unnecessary argument, updating the stmmac driver
appropriately.
