drm/atomic: Pass the full state to CRTC atomic begin and flush
...
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's start convert all the remaining helpers to provide a consistent
interface, starting with the CRTC's atomic_begin and atomic_flush.
The conversion was done using the coccinelle script below, built tested on
all the drivers and actually tested on vc4.

drm/atomic: Pass the full state to CRTC atomic enable/disable
...
If the CRTC driver ever needs to access the full DRM state, it can't do so
at atomic_enable / atomic_disable time since drm_atomic_helper_swap_state
will have cleared the pointer from the struct drm_crtc_state to the struct
drm_atomic_state before calling those hooks.
In order to allow that, let's pass the full DRM state to atomic_enable and
atomic_disable. The conversion was done using the coccinelle script below,
built tested on all the drivers and actually tested on vc4.
