the currently selected media is of type IFM_AUTO as auto-negotiation
doesn't need to be kicked anyway.
- Don't set MIIF_NOISOLATE so qsphy(4) can be used in configurations
with multiple PHYs. There doesn't seem to be a problem with isolating
QS6612 per se nor in combination with the NICs they're used with.
- Use mii_phy_add_media() instead of mii_add_media() so the latter can
be eventually retired.
- Take advantage of mii_phy_setmedia().

well as is, so - just fetch current status upon MII_TICK.
Also do IFM_INST verification at the top of *_service() then doing it
separately for every case in switch.
acphy: do not read MII_ACPHY_DIAG twice, there is nothing latching.
qsphy: always fetch actual link status from MII_QSPHY_PCTL.

Rename mii_phy_auto_stop() mii_phy_down().
Introduce mii_down(), use it from nge. Do not indirect it to 19 identical
case's in 19 switchstatements like NetBSD did.
. Make internal service routines static.
. Use a consistent ordering of checks in MII_TICK. Do the work in the
mii_phy_tick() subroutine if appropriate.
. Call mii_phy_update() to trigger the callbacks.
