fbdev: add FBIOCOPYAREA ioctl
Based on the patch authored by Ali Gholami Rudi at https://lkml.org/lkml/2009/7/13/153 Provide an ioctl for userspace applications, but only if this operation is hardware accelerated (otherwide it does not make any sense). Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com>
