drm/atomic: Pass the full state to planes atomic disable and update

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 convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.

The conversion was done using the coccinelle script below, built tested on
all the drivers.
