drm/atomic-state-helper: Rename __drm_atomic_helper_crtc_state_reset()

Browse Source 
__drm_atomic_helper_crtc_state_reset() is used to initialize a newly
allocated drm_crtc_state, and is being typically called by the
drm_crtc_funcs.reset implementation.

Since we want to consolidate DRM objects state allocation around the
atomic_create_state callback that will only allocate and initialize a
new drm_crtc_state instance, we will need to call
__drm_atomic_helper_crtc_state_reset() from both the reset and
atomic_create hooks.

To avoid any confusion, we can thus rename
__drm_atomic_helper_crtc_state_reset() to
__drm_atomic_helper_crtc_state_init().
