drm: Rename plane->state variables in atomic update and disable ...
Some drivers are storing the plane->state pointer in atomic_update and
atomic_disable in a variable simply called state, while the state passed
as an argument is called old_state.
In order to ease subsequent reworks and to avoid confusing or
inconsistent names, let's rename those variables to new_state.
This was done using the following coccinelle script, plus some manual
changes for mtk and tegra.
