====================
split phylink PCS operations

This series splits the phylink_mac_ops structure so that PCS can be
supported separately with their own PCS operations, separating them
from the MAC layer.  This may need adaption later as more users come
along.

v2: change pcs_config() and associated called function prototypes to
only pass the information that is required, and add some documention.

v3: change phylink_create() prototype
