changing these PHY drivers to no longer unconditionally advertise
support for flow control but only if the selected media has IFM_FLOW

the NIC drivers as well as the PHY drivers to take advantage of the
mii_attach() introduced in r213878 to get rid of certain hacks. For
the most part these were:
- Artificially limiting miibus_{read,write}reg methods to certain PHY
addresses; we now let mii_attach() only probe the PHY at the desired
address(es) instead.
- PHY drivers setting MIIF_* flags based on the NIC driver they hang
off from, partly even based on grabbing and using the softc of the
parent; we now pass these flags down from the NIC to the PHY drivers
via mii_attach(). This got us rid of all such hacks except those of
brgphy() in combination with bce(4) and bge(4), which is way beyond
what can be expressed with simple flags.
While at it, I took the opportunity to change the NIC drivers to pass
up the error returned by mii_attach() (previously by mii_phy_probe())
and unify the error message used in this case where and as appropriate
as mii_attach() actually can fail for a number of reasons, not just
because of no PHY(s) being present at the expected address(es).

different PHY instance being selected and isolation out into the wrappers
around the service methods rather than duplicating them over and over
again (besides, a PHY driver shouldn't need to care about which instance
it actually is).
- Centralize the check for the need to isolate a non-zero PHY instance not
supporting isolation in mii_mediachg() and just ignore it rather than
panicing, which should sufficient given that a) things are likely to
just work anyway if one doesn't plug in more than one port at a time and
b) refusing to attach in this case just leaves us in a unknown but most
likely also not exactly correct configuration (besides several drivers
setting MIIF_NOISOLATE didn't care about these anyway, probably due to
setting this flag for no real reason).
- Minor fixes like removing unnecessary setting of sc->mii_anegticks,
using sc->mii_anegticks instead of hardcoded values etc.

Rename mii_phy_auto_stop() mii_phy_down().
Introduce mii_down(), use it from nge. Do not indirect it to 19 identical

. Use a consistent ordering of checks in MII_TICK. Do the work in the

I have not done serious performance testing with this driver. I know
it works, and I want it under CVS control so I can keep tabs on it.
Note that there's no serious mutex stuff in here yet either: I need
to talk more with jhb to figure out the right way to do this. That
said, I don't think there will be any problems.
This driver should also work on the alpha. It's not turned on in
GENERIC.
