Subject: [PATCH v2 net-next 07/15] net: pcs: xpcs: introduce xpcs_create_pcs_fwnode()

Introduce a wrapper over xpcs_create_fwnode() that doesn't return the
specific dw_xpcs pointer type, but the generic phylink_pcs pointer type.
For example, the NXP SJA1105 driver might use this if it has a
pcs-handle - it is already a user of xpcs_create_pcs_mdiodev().
