drm: Add TODO item for requesting memory regions
Add a TODO item about requesting memory regions for each driver. The current DRM drivers don't do this consistently.

+Request memory regions in all drivers
+-------------------------------------
+
+Go through all drivers and add code to request the memory regions that the
+driver uses. This requires adding calls to request_mem_region(),
+pci_request_region() or similar functions. Use helpers for managed cleanup
+where possible.
+
+Drivers are pretty bad at doing this and there used to be conflicts among
+DRM and fbdev drivers. Still, it's the correct thing to do.
