Update e100 net driver: 

Feedback from review by Arjan @ Redhat:
o Cleanup: Removed unneccesary #ifdef/#endif wrappers for features 
  already part of kernel.
o Bug fix: Added read-behind-write calls to post writes before delays.
o Cleanup: added "e100" prefix to all driver messages.
o Cleanup: removed unnecessary barrier() call because spin_unlock
  already implies a barrier.
o Cleanup: removed __NO_VERSION__
o Cleanup: fixed some spelling mistakes.
o Cleanup: removed some proprietary /proc entries.
