drm/fb-helper: Mark screen buffers in system memory with FBINFO_VIRTFB
Mark screen buffers in system memory with FBINFO_VIRTFB. Otherwise, fbdev
deferred I/O marks mmap'ed areas of system memory with VM_IO. (There's an
inverse relationship between the two flags.)
For shadow buffers, also set the FBINFO_READS_FAST hint.
v3:
* change FB_ to FBINFO_ in commit description
v2:
* updated commit description (Daniel)
* added Fixes tag
