drm/vram: add vram-mm debugfs file

Wire up drm_mm_print() for vram helpers, using a new
debugfs file, so one can see how vram is used:

   # cat /sys/kernel/debug/dri/0/vram-mm
   0x0000000000000000-0x0000000000000300: 768: used
   0x0000000000000300-0x0000000000000600: 768: used
   0x0000000000000600-0x0000000000000900: 768: used
   0x0000000000000900-0x0000000000000c00: 768: used
   0x0000000000000c00-0x0000000000004000: 13312: free
