Very similar to Francois Romieu's fixes for cirrusfb, here we:
* Provide meaningful error values from radeonfb_pci_register()
* Fix unbalanced pci_enable_device()
* Fix unbalanced fb_alloc_cmap()
* Fix a failure-case bug where we accidentally memset_io(0, 0, size);
* Use pci_request_regions() instead of request_mem_region()
