Introduce support for the AM64 DDRSS controller which uses the 16bit variation of the controller. This controller shares much functionality with the existing J721e support, so this patch introduces only the new code needed for am64 specific support from "_16bit_" files with headers under "16bit/" 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. Signed-off-by: Dave Gerlach <d-gerlach@ti.com>

The RAM subsystem adds a small amount of overhead to the image.

If this is acceptable and you have a need to use RAM drivers in
|

setting up RAM (e.g. SDRAM / DDR) within SPL.
