[PATCH 2/2] drm/omapdrm: Fix console with deferred ops

[Tony Lindgren <tony@atomide.com>]

Commit 95da53d63dcf ("drm/omapdrm: Use regular fbdev I/O helpers")
broke console because there is no damage handling in fb_sys_write()
unlike we have in drm_fb_helper_sys_write().

Let's fix the issue by using deferred ops with fb helpers for damage.
