net: pcs: xpcs: add xpcs_create_mdiodev()

Browse source

Add xpcs_create_mdiodev() to simplify the creation of the mdio device
associated with the XPCS. In order to allow xpcs_destroy() to clean
this up, we need to arrange for xpcs_create() to take a refcount on
the mdiodev, and xpcs_destroy() to put it.

Adding the refcounting to xpcs_create()..xpcs_destroy() will be
transparent to existing users of these interfaces.
