drm/atomic-helper: Extract drm_atomic_helper_calc_timestamping_constants()
Put the vblank timestamping constants update loop into its own
function. It has no business living inside
drm_atomic_helper_update_legacy_modeset_state() so we'll be wanting
to move it out entirely. As a first step we'll still call it
from drm_atomic_helper_update_legacy_modeset_state().
v2: Drop comment about 'legacy state' in the new function
