Pbus Defines Template, pbusdefn-template.h

The following is a template pbusdefn.h file. In an application that uses the Pbus control code, this template is modified to reflect the memory locations of the controller ports. Additionally, this file provides a stub for the definition of application-specific Pbus addresses.
