[PATCH v3 net-next 00/13] Port the SJA1105 DSA driver to XPCS

From: Vladimir Oltean <vladimir.oltean@nxp.com>

As requested when adding support for the NXP SJA1110, the SJA1105 driver
could make use of the common XPCS driver, to eliminate some hardware
specific code duplication.

This series modifies the XPCS driver so that it can accommodate the XPCS
instantiation from NXP switches, and the SJA1105 driver so it can expose
what the XPCS driver expects.

Tested on NXP SJA1105S and SJA1110A.

Changes in v3:
None. This is a resend of v2 which had "changes requested" even though
there was no direct feedback.

Changes in v2:
- fix module build (pcs-xpcs-nxp.c is not a different module so this
  means that we need to change the name of pcs-xpcs.ko to pcs_xpcs.ko).
- delete sja1105_sgmii.h
- just check for priv->pcs[port] instead of checking the PHY interface
  mode each time.
- add the 2500base-x check in one place where it was missing (before
  mdio_device_create)
- remove it from a few places where it is no longer necessary now that
  we check more generically for the presence of priv->xpcs[port]
