The power-domains exposed by AOSS QMP node are used to notify the Always on Subsystem (AOSS) that a particular co-processor is up/down. These co-processors enter low-power modes independent to that of the application processor and their states are expected to remain unaltered across system suspend/resume cycles. To achieve this behavior let's drop the power-domain bindings and replace them with generic qmp_send interface instead.
