* Makefile.am, preinstall.am,
* 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
* irq/irq.c, include/gen2.h:
removed _BSP_vme_bridge_irq variable and BSP_PIC_DO_EOI definition.
Support for VME IRQ software priorities was incomplete/incorrect
on this BSP.
