drm/atomic-helpers: Update vblank timestamping constants 

The atomic helpers don't call drm_calc_timestamping_constants, which
is a regression compared to the crtc helpers. Fix this.

Noticed while reviewing i915 atomic patches from Maarten.

v2: Also check state->enable to avoid a warning in dmesg. Reported by
Maarten.
