Split the main power supply into managment and two user areas.  Mostly
put back together again from phase2, although only the gpio testbench
has been updated, and the gpio tesbench is currently not passing although
most signals seem to be right.  Modified the memory map to allow for an
additional word in the management I/O GPIO read/write data, and rewrote
the code to handle any number of I/Os in the user space, expanding the
memory map by one word for every 32 user GPIO pads (there are currently
37 user GPIO pads specified, so this change resolves issues with the
upper 5 pads;  the last phase2 design defined only 32 user I/O pads).
