miiphy: Note that miiphy_* API is deprecated

We want to move everything to phylib, and we definitely don't want
new drivers using the miiphy infrastructure.

 ---------------------------
 
+What:	Users of the legacy miiphy_* code
+When:	undetermined
+
+Why:	We now have a PHY library, which allows everyone to share PHY
+	drivers. All new drivers should use this infrastructure, and
+	all old drivers should get converted to use it.
+
+Who:	Andy Fleming <afleming@freescale.com> and driver maintainers
+
+---------------------------

 What:	boards with xxx_config targets in top level Makefile
 When:	Release v2012.03
