  Log:
  MFP4: Changes to hopefully make the new power code work better
  
  o Rather than just try to turn off EXCA_INTR_RESET, set the entire register
    to 0.  This is slightly faster, and a better hammer.
  o Move attempted clearing of the output enable (EXCA_PWRCTL_OE) back to
    after we turn off the power.  Modify it to write 0 so that we don't get
    Bad Vcc messages on TI bridges (untested, but ru@ sent me a similar patch)
    while at the same time avoiding interrupt storms on Ricoh bridges (tested
    by me on my Sony).
  
  # Many of my observations of 'breakage' for this patch are due to some bug
  # in the load/unload of cbb.ko unlreated to this change.  I'll be investigating
  # and fixing that bug in the fullness of time.
