  Log:
  Fix:
  - Missing cpu_to_scr() added (endian-ness).
  
  Improvement (fix|workaroung??):
  - Blindly firing a PPR can lead to some messy situations due to
    various causes or misfeatures, for example:
    * The 53C1010-[33|66] supports offset 62 in DT mode, but only
      offset 31 in ST mode. As a result, a PPR(DT, offset 62)
      responded with PPR(ST, any offset > 31) must be rejected.
    * A device that doesn't know about PPR should reject it, but
      may also be confused by this message.
    When a PPR encounters problems, the driver now patches the goal
    transfer settings for legacy negotiations to be performed later
    with the offending target. This give a chance for bad situations
    to be fixed automagically.
