Andrew F. Davis 65f7b81728 ti: k3: common: Use coherent memory for shared data
HW_ASSISTED_COHERENCY implies something stronger than just hardware
coherent interconnect, specifically a DynamIQ capable ARM core.

For K3, lets use WARMBOOT_ENABLE_DCACHE_EARLY to enable caches early
and then let the caches get shut off on powerdown, to prevent data
corruption we also need to USE_COHERENT_MEM so that any accesses to
shared memory after this point is only to memory that is set as
non-cached for all cores.
