Thomas Zimmermann 22fd2377b9 drm/fbdev-dma: Select FB_DEFERRED_IO ...

commit 67c40c9b2e upstream.

Commit 808a40b694 ("drm/fbdev-dma: Implement damage handling and
deferred I/O") added deferred I/O for fbdev-dma. Also select the
Kconfig symbol FB_DEFERRED_IO (via FB_DMAMEM_HELPERS_DEFERRED). Fixes
build errors about missing fbdefio, such as
