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.
