* Makefile.am, preinstall.am, include/bsp.h,
* vme/vmeconfig.c (removed), vme/VMEConfig.h (added):
cleaned up vme support - use files from libbsp/powerpc/shared/vme
and define BSP specifica in VMEConfig.h.
Use VME DMA support implemented by vmeUniverse and
libbsp/powerpc/shared/vme/vme_universe_dma.c
