Modified Files:
        src/sys/dev/pci: pccbb.c

Log Message:
A bunch of random cleanup:
* Like the i82365 code, add a "delay" function that uses tsleep() to wait, and
  use this in the socket enable/disable paths.  This gets rid of the annoying
  system pauses during card insertion and removal.  (There are still some
  issues related to this in various drivers -- notably big delay()s in wi and
  xi.)
* Move the power-change delay out of pccbb_power() and into the PCMCIA backend
  code -- specifically, once in the disable path and once in the enable path.
  We were being pretty schizo about this before.  Make these use tsleep().
  (Note: This should be safe because card insertion/removal is handled by a
  kernel process, not in an interrupt handler.  It works for me with
  DIAGNOSTIC.)
* If we get a "bad Vcc" error, attempt to force the socket to power off, and
  return an error.  If we don't do this, we will get "bad Vcc" errors forever
  and never be able to use another card without rebooting, which is dumb.
  XXX I haven't been able to test this very well, because it doesn't fail for
  me in the first place.  :-)
* Clean up the socket mappings earlier in the enable path.
* Try to be consistent about clearing PWRCTL (which contains OE) before turning
  off power.
