Merge branch 'sja1105-cleanups'

Russell King says:

====================
convert sja1105 xpcs creation and remove xpcs_create

This series of three patches converts sja1105 to use the newly
provided xpcs_create_mdiodev(), and as there become no users of
xpcs_create(), removes this function from the global namespace to
discourage future direct use.
