private DMA buffers / mach64-drm - try 1
Add DRM_PCI_READ_ONLY flag in drmBufDescFlags.
When drm_mmap_dma sees this flag (set from drmAddBufs), it maps the PCI DMA
buffers as read-only (I just copied the code from drm_mmap).
An additional flag is needed, since PCI DMA buffers do not have an associated
map.
