* 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
