Log Message:
Pull up the following revisions (all via patch), requested by msaitoh
in ticket #1410:

        sys/dev/mii/makphy.c                            1.67,1.69-1.72
        sys/dev/mii/makphyvar.h                         1.3-1.4

- Add I347-AT4 support.
- Add three workarounds for QEMU e1000:
  - QEMU sets BMSR_EXTSTAT but the access to register 15 fails.
    Set EXTSR_1000TFDX and EXTSR_1000THDX if the access failed in the
    attach function. It's just a cosmetic change.
  - Marvell 88E1[01]11 have the Fiber/Copper auto selection feature,
    but QEMU doesn't implement it. If the register access failed,
    the media is regarded as copper only. It's just a cosmetic change.
  - QEMU provides the PHY specific status register at 0x11 but the
    link indication bit (PSSR_LINK) is always 1. It causes
    "virsh domif-setlink xxx yyy down" doesn't work. To avoid this
    problem, read the BMSR and check the BMSR_LINK bit. Add
    MAKPHY_QUIRK_PSSR_LINK bit for this quirk. Set it if MII_EXTSR
    doesn't exist because it's one of the case of QEMU.
- Reduce the number of access to the ESSR register. One of the reason
  is that the register is not implemented on QEMU. Another reason is
  that it's not required to access the register if the device is in
  the copper only mode.
