Introduce a new version of the ddr driver which has the ability to support different variations of the controller. Also introduce support for the 32bit variation of the controller which is what was already supported by the previous version used for J721e and J7200. Signed-off-by: Dave Gerlach <d-gerlach@ti.com>
