Add optional property node 'arm,malidp-arqos-value' for the Mali DP500.
This property describe the ARQoS levels of DP500's QoS signaling.

change in v3:
        - correction the describe of the node

Sure, actually, here should be use a u32 value....

The older description was correct, sorry, I should be
Correction the example node define...

'integer of u32 value describing the ARQoS levels of DP500's QoS signaling',
