Add debugfs support to make it easier to print debug information about the dma-buf buffers.

I like thie idea,

/home/airlied/devel/kernel/drm-2.6/drivers/base/dma-buf.c: In function ‘dma_buf_describe’: /home/airlied/devel/kernel/drm-2.6/drivers/base/dma-buf.c:563:5: warning: format ‘%d’ expects argument of type ‘int’, but argument 6 has type ‘long int’ [-Wformat] /home/airlied/devel/kernel/drm-2.6/drivers/base/dma-buf.c: At top level: /home/airlied/devel/kernel/drm-2.6/drivers/base/dma-buf.c:528:123: warning: ‘dma_buf_init’ defined but not used [-Wunused-function]

not sure my compiler does though.
