AMD SB900: fix warnings

Add a prototype to a .h file
    Remove an unused file (GppHp.c) from the build by deleting it from the
      makefile. I left the file since this is vendorcode. This is the code
      for PCIe hotplug.
    Inside GppHp.c, make functions not called from outside static.
      This obviously isn't important since the file isn't used, but for
      the sake of the cleanup I thought I'd go ahead with it...

This was tested with the torpedo build.

This fixes these warnings:
