Routine Description:
This function returns the system interrupt vector and IRQL level
corresponding to the specified bus interrupt level and/or vector. The
system interrupt vector and IRQL are suitable for use in a subsequent call
to KeInitializeInterrupt.
Arguments:
BusHandle - Per bus specific structure
Irql - Returns the system request priority.
Affinity - Returns the system wide irq affinity.
Return Value:
Returns the system interrupt vector corresponding to the specified device.
