- In acphy_service() for the MII_TICK case don't bother to check whether
  the currently selected media is of type IFM_AUTO as auto-negotiation
  doesn't need to be kicked anyway.
- Fix a whitespace nit.
- Probe another Altima PHY, which is a AC101 workalike and integrated
  in at least ADMtek ADM8511 but apparently is not mentioned in any
  publically available data sheet so the actual identifier is unknown.
- Don't set MIIF_NOISOLATE so acphy(4) can be used in configurations
  with multiple PHYs. There doesn't seem to be a problem with isolating
  AC101 and workalikes 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().
