Revert "fb_defio: Remove custom address_space_operations"
Commit ccf953d8f3d6 makes framebuffers which use deferred I/O stop
displaying updates after the first one. This is because the pages
handled by fb_defio no longer have a page_mapping(). That prevents
page_mkclean() from marking the PTEs as clean, and so writes are only
noticed the first time.
