drm/atomic: Save flip flags in drm_crtc_state
Allows using atomic flip helpers for drivers
using ASYNC flip.
Remove ASYNC_FLIP restriction in helpers and
caches the page flip flags in drm_crtc_state
to be used in the low level drivers.
v2:
Resending the patch since the original was broken.
v3:
Save flag in crtc_state instead of plane_state
v4:
Reset the flag before using again.
v5:
Fix type in header.
Rename the field to pageflip_flags.
Remove unrelated hunk.
