Pin field is 1-origin and 0 means no PCI pin.  0/14 are reasonable for 0x8a
case.

0. pin/line fields are merely "informational" for SW and brings no functional
change in PCIIDE HW.
1. "no PCI pin for 0x8a" is a part of PCIIDE specification. 
2. It's the matter of SW if it respects the line field.  Clearing the field is
insignificant.
