Interrupt D Pin Route (INTDPR): Indicates which PIRQ routing used for INTD#.
Legal values are [0x0-0x7] corresponding to PIRQ[A-H]. For example, INTD# will be
routed to PIRQG if this field is set to 0x6.

Interrupt C Pin Route (INTCPR): Indicates which PIRQ routing used for INTC#. Legal
values are [0x0-0x7] corresponding to PIRQ[A-H]. For example, INTC# will be routed to
PIRQG if this field is set to 0x6.

Interrupt B Pin Route (INTBPR): Indicates which PIRQ routing used for INTB#. Legal
values are [0x0-0x7] corresponding to PIRQ[A-H]. For example, INTB# will be routed to
PIRQG if this field is set to 0x6.

Interrupt A Pin Route (INTAPR): Indicates which PIRQ routing used for INTA#. Legal
values are [0x0-0x7] corresponding to PIRQ[A-H]. For example, INTA# will be routed to
PIRQG if this field is set to 0x6.
