drm/fb-helper: Add drm_fb_helper_set_suspend_unlocked()
This adds a function that also takes the console lock before calling fb_set_suspend() in contrast to drm_fb_helper_set_suspend() which is a plain wrapper around fb_set_suspend(). Resume is run asynchronously using a worker if the console lock is already taken. This is modelled after the i915 driver.
