+  Macro that converts PCI Segment and I/O Port to an address that can be

+  passed to the I/O Library functions.

+  

+  Computes an address that is compatible with the I/O Library functions.  

+  The unused upper bits of Segment, and Port are stripped prior to the 

+  generation of the address.

+  

+  @param  Segment   PCI Segment number.  Range 0..65535.

+  @param  Port      I/O Port number.  Range 0..65535.

+  

+  @return An address that the I/o Library functions need.
