Update the ITE IT8500 EC support to match the current state of the flashrom-chromium tree

This code has been deployed and tested to work on the Cr-48.
There are a few caveats, though:
- The boot BIOS straps register must be modified to select LPC. This
  can be done with the "select_bbs.sh" script (Install iotools at
  http://code.google.com/p/iotools/ before using select_bbs).
- It is very important to disable power management daemons before
  running flashrom on this EC. I commented out the brute force method
  we use in the Chromium OS branch that disables powerd, since IIRC
  Carl-Daniel has a better approach in the works.
- Due to dependencies which may be introduced by the OEM/ODM EC
  firmware, the code is not guaranteed to work for anything other than
  the Cr-48.

Corresponding to flashrom svn r1263.

Carl-Daniel comments:
Code is not hooked up yet because probing needs to be sorted out.
