Add IT8212F as programmer

This PCI PATA controller can use 3V parallel flash up to 128 kB.

My card was identified as:
  PCI 1283:8212, subsystem 1283:0001.

and labelled as:
  Innovision Multimedia LTD.
  EIO ATA133 RAID
  (DM-8401 Ver A)

This particular card did not require setting of any GPIO signals to
enable flash writing. My card has Pm39LV512 in PLCC32 package without
socket.

Rebased by Stefan (automatic cleanup, some PCI changes, changed
enable bit handling). Committed with test state NT because the
rebased version was not tested on real hardware (yet).

Corresponding to flashrom svn r1812.
