MFC r241983-241985:
r241983:
  Do not hardcode phy address. Multi-port controllers use different phy
  address.

r241984:
  Ethernet@WireSpeed is defined for 1000baseT adapter to establish a
  link at a lower speed so enabling it for fiber adapters is wrong.
  Fix the issue by setting BGE_PHY_NO_WIRESPEED such that brgphy(4)
  wouldn't enable the feature.
  While I'm here move PHY specific feature/bug configuration to new
  location(just before mii attach) for readability.

r241985:
  For fast ethernet controllers, Ethernet@WireSpeed is not defined so
  explicitly set BGE_PHY_NO_WIRESPEED flag.
