Subject: [PATCH 1/5] fec: Place the phy regulator in the private structure

Instead of using a local reg_phy structure, let's put it inside the private
structure, so that we are able to have access to the regulator structure even
when we are outside fec_probe().

This is in preparation for controlling the FEC PHY regulator in the suspend and
resume functions.
