SILI - Increase hard -> soft PM target delay to 5 seconds

* Unfortunately it looks like we have to seriously increase the delay
  between doing a hard reset via the PM to a target and initiating
  the softreset.

  The Silicon Image chip appears to brick the port if its softreset
  collides with the target device.  There is no way to fix it other
  then hard-resetting the port (which causes the PM to reset as well).
