With AM64x supporting only K3_NAV_RINGACC_RING_MODE_RING or the exposed
ring mode, all other K3 SoCs have also been moved to this common
baseline. Therefore drop other modes such as
K3_NAV_RINGACC_RING_MODE_MESSAGE (and proxy) to save on SPL footprint.
There is a saving of ~800 bytes with this change for am65x_evm_r5_defconfig.

AM64 dual mode rings are modeled as pair of Rings objects which has common
configuration and memory buffer, but separate real-time control register
sets for each direction mem2dev (forward) and dev2mem (reverse).
AM64 rings must be requested only using k3_ringacc_request_rings_pair(),
and forward ring must always be initialized/configured. After this any
other Ringacc APIs can be used without any callers changes.

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
