Introduce support for the AM64 DDRSS controller through a common driver
for both am64 and j721e. This controller shares much functionality with
the existing J721e support, so this patch refactors the driver such that
the am64 specific comes from "_16bit_" files with headers uner "16bit/"
include path, and j721e support comes from "_32bit_" files with headers
under the "32bit/" include path.
Also add a CONFIG_K3_AM64_DDRSS option to the choice required for use
with CONFIG_K3_DDRSS to allow selecting AM64 support.
