[PATCH 2/2] drm/panel: ili9322: Convert to use maple tree register cache

Mark Brown broonie at kernel.org

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.
