drm_hwcomposer: add checks for tegra hardware limitation
Current approach is to allow atomic_check figure out any issues with
composition strategy and fallback to squash if there the atomic_check
fails. This leads to issues when there's a protected content as it
cannot be handled in squash.
Adding a new provisioning stage to check for hardware limitations and
address them early so a proper fall back can be in place.
