The direct message response received by the SPMD upon a CPU_OFF power
management operation must be a framework message. If message indicates
SPMC denied the CPU_OFF operation, SPMD shall panic.
However, if SPMC does not support receiving power management
related framework messages from SPMD, it will return FFA_ERROR.
In such case, SPMD takes an implementation defined choice to ignore the
the FFA_ERROR and proceed with power management operation.
