[PATCH 0/3] scmi-cpufreq: Set transition_delay_us

[Pierre Gondois]

policy's fields definitions:
`transition_delay_us`:
The minimum amount of time between two consecutive freq. requests
for one policy.
`transition_latency`:
Delta between freq. change request and effective freq. change on
the hardware.

cpufreq_policy_transition_delay_us() uses the `transition_delay_us`
value if available. Otherwise a value is induced from the policy's
`transition_latency`.

The scmi-cpufreq driver doesn't populate the `transition_delay_us`.
Values matching the definition are available through the SCMI
specification.
Add support to fetch these values and use them in the scmi-cpufreq
driver.

  firmware: arm_scmi: Populate perf commands rate_limit
  firmware: arm_scmi: Populate fast channel rate_limit
  cpufreq: scmi: Set transition_delay_us
