CMP devices become immediately disabled after their parent CMU is disabled (26586749)

As shown in the following example, if you set the requested_config_state property to disabled for a powered on component (for example, a CMIOU), the current_config_state setting for that component's children (for example, a CMIOU's CMPs) will immediately appear to be disabled even though the parent and children are not effectively disabled until next host power cycle.

-> set /SYS/CMU5 requested_config_state=Disabled 
show /SYS/CMU5
        requested_config_state = Disabled
        current_config_state = Enabled
show /SYS/CMU5/CMP0
        requested_config_state = Disabled
        current_config_state = Disabled
        disable_reason = Parent resource disabled
