PCI Request/Grant Priority Select.
When set, two sets of PCI request/grant lines are to be used for PCI arbi-
tration. USB and IDE masters are moved to the secondary P_REQ_2#/
P_GNT_2# request/grant pair. The LPC master remains on the primary
request and grant lines P_REQ_1#/P_GNT_1#.
When clear, only one pair of request/grant pairs is used for arbitration.
The LPC/USB/IDE will share the same PCI request and grant lines
P_REQ_1#/P_GNT_1#.
