+ DispatchContext - Pointer to the dispatch function's context.
+ The caller fills this context in before calling

+ function the Power Button SMI phase for which the dispatch
+ function should be invoked.

+ with the parent Sx state SMM driver.
+
+ Returns:
+ EFI_SUCCESS - The dispatch function has been successfully
+ registered and the SMI source has been enabled.
+ EFI_DEVICE_ERROR - The driver was unable to enable the SMI source.
+ EFI_OUT_OF_RESOURCES - Not enough memory (system or SMM) to manage this
+ child.
+ EFI_INVALID_PARAMETER - DispatchContext is invalid. The Power Button SMI
+ phase is not within valid range.
