ram: k3-ddrss: Introduce common driver with J7 SoC support

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.
