cpukit/libpci references BSP headers.

On the no-preinstall branch of ​https://git.rtems.org/chrisj/rtems.git/ the build fails with:

Is there anything in the implementations that is BSP, not architecture, specific? They could be moved to cpukit if we have confidence they can be implemented always that way.

Or they can be real methods provided by the bsl

Sorry I do not know.
