imp e9400557a5 This is a major reworking of the AX88x90 support.
o Introduce new chip_type AX88790.  There's a few places we need to know the
  exact chip for workaronds.
o Explain the AX88190 workaround for the ISR bits being stuck, and don't
  apply them to the AX88790.  The datasheet says the bits are fixed, and
  experience confirms.
o Fix mii bit-bang read code to read and discard the 'floating' bit.
o Remove empty ed_pccard_ax88x90_mii_reset routine
o Report error from mii_phy_probe
o Don't use ed_probe_Novel_generic for ax88x90 chips.  It puts them into
  an odd state sometimes.  Instead, use a more stream-lined version that
  avoids the trouble spots.  This was copied and tweaked from the original.
o Move chip reset into its own routine.
o Minor code optimiation on getting MAC address
o Add code for coping with AX88790 cards that are in power down state and
  need to be kicked before the PHY registers for the internal phy read right.
o Remove ugly cap of PHYs at 17.
o For AX88790, we need to set a special bit for accessig phy 16 (the internal
  phy) and clear it for all others according to a chip erratum.
o streamline the bit-bang code for AX88x90: the delays aren't needed according
  to the datasheet timing diagrams and also the Linux driver
o Fix minor bit definition for direction bit.
o Generally: Some comments reformatted
o Only try the toshiba probe on cards labelled as toshiba

# From another Akihabara card (this one from a few years ago from a
# friend in Japan).  Fix the Corega FEther II PCC-TXD.  This one is
# still on sale new, as of a few weeks ago.  should fix all other AX88x90
# based cards, but I have some testing left to finish on my collection...
