QoS bit mapping are common across all K3 SoCs so move those defines to common header file (k3_qos.h). This ensures that we do not define these for each SoC.

This all seem like it could be made into some macro, something like
#define K3_QOS(qos, orderid, asel, epriority, virtid, atype) \ (qos << 0 | \ orderid << 4 | \ asel << 8 | \ etc..
Then use that instead of raw values. That might also make it more clear we are setting the other values to 0 when we are setting these registers:
.val = K3_QOS(0, 15, 0, 0, 0, 3),
This sounds good to me too and to be clear, move in one patch, clean up macro follow-up patch in this series.
