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.
