drm/atomic-helper: Massage swap_state signature somewhat

- dev is redundant, we have state->atomic - add stall parameter, which must be set when swapping needs to stall for preceeding commits to stop looking at ->state pointers. Currently all drivers need this to be, just prep work for a glorious future. v2: Rebased on top of commit e7cf096 Author: Gerd Hoffmann <[email protected]> Date: Tue May 31 08:50:47 2016 +0200 virtio-gpu: add atomic_commit function Cc: Gerd Hoffmann <[email protected]> Reviewed-by: Maarten Lankhorst <[email protected]> Cc: Maarten Lankhorst <[email protected]> Signed-off-by: Daniel Vetter <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected] Link: http://patchwork.freedesktop.org/patch/msgid/[email protected]
