drm: Use state helper instead of plane state pointer in atomic_check
Many drivers reference the plane->state pointer in order to get the
current plane state in their atomic_check hook, which would be the old
plane state in the global atomic state since _swap_state hasn't happened
when atomic_check is run.
Use the drm_atomic_get_old_plane_state helper to get that state to make
it more obvious.
This was made using the coccinelle script below:

identifier helpers;
identifier func;

static struct drm_plane_helper_funcs helpers = {
...,
.atomic_check = func,
...,
};
