firmware: arm_scmi: Implement clock get permissions
ARM SCMI v3.2 introduces clock get permission command. To implement the
same let us stash the values of those permissions in the scmi_clock_info.
They indicate if the operation is forbidden or not.
If the CLOCK_GET_PERMISSIONS command is not supported, the default
permissions are set to allow the operations, otherwise they will be set
according to the response of CLOCK_GET_PERMISSIONS from the SCMI
platform firmware.
