[PATCH v2 0/3] Enable QoS configuration on X1E80100

[Raviteja Laggyshetty <raviteja.laggyshetty@oss.qualcomm.com>]

This series enables QoS configuration for QNOC type device which
can be found on X1E80100 platform. It enables QoS configuration
for master ports with predefined priority and urgency forwarding.
This helps in prioritizing the traffic originating from different
interconnect masters at NOC (Network On Chip).

The system may function normally without this feature. However,
enabling QoS helps optimize latency and bandwidth across subsystems
like CPU, GPU, and multimedia engines, which becomes important in
high-throughput scenarios. This is a feature aimed at performance
enhancement to improve system performance under concurrent workloads.

Changes in v2:
 - Update the dt-bindings to make the clock property optional, since the
   device can operate without QoS, preserving the backward compatibility.
