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.
