PortPowerControlMask: Each bit indicates whether a port is
affected by a global power control command when
PowerSwitchingMode is set. When set, the power state of the port
is only affected by per-port power control (Set/ClearPortPower).
When cleared, the port is controlled by the global power switch
(Set/ClearGlobalPower). If the device is configured to global
switching mode (PowerSwitchingMode = 0), this field is not valid.
