[PATCH v2 24/37] drm/msm/mdp5: Switch to drm_atomic_get_new_crtc_state()

[Maxime Ripard <mripard@kernel.org>]

The msm atomic_check implementation uses the deprecated
drm_atomic_get_existing_crtc_state() helper.

This hook is called as part of the global atomic_check, thus before the
states are swapped. The existing state thus points to the new state, and
we can use drm_atomic_get_new_crtc_state() instead.
