Merge with NetBSD:

o move common support functions for phy drivers from mii.c to mii_physubr.c,
	so that they are not includes if no PHY is configured
o Clean up the code that adds media a little, and make media selection
	table-driven in preparation for some other changes to be made.
o Don't add any loopback versions of media, for now.
o Add mii_down(), which is used by MAC drivers to inform PHYs that the
	interface is now down.  PHYs use this to cancel pending asynchronous
	operations.
o Add OUI for Enable Semiconductor.
o New Driver for TDK TSC78Q2120 PHY
