description:
Backout r1.18.
  Don't change IRQ porality.  The Real-machines encounters interrupt storm.
  OK slp@.

  I assum configured it from boot-loader already.  However need polarity
  information, if not.  Shall we implement to use prop_dictionary_{set,get}?

  Also this case, re-initialized to LAN9118_IRQ_CFG without
  LAN9118_IRQ_CFG_POL in lan9118_init().  I think, again interrupt storm on
  QEMU.
