Some workloads on Kodiak can exhaust FastRPC sessions when multiple
compute clients open contexts concurrently, leading to -EBUSY failures.

Describe the compute context bank with qcom,nsessions = <5> so the
driver can provision enough session slots for the compute-cb instance.
This is a software property, so it probably should not have been added
to the DT in the first place. Can we replace it with the driver code,
allocating more sessions to the last CB?
