MdePkg: Reference new definitions for Management Mode.

Browse Source 
In PI 1.5 version, system management mode name(SMM) has been changed
to Management Mode(MM). It impacts the current code which still use
SMM/Smram/SMI keywords. This patch update the original files which
related to old SMM modules, also keep the compatible with old SMM
related drivers.

Provides the parent dispatch service for a given Sx source generator.
typedef EFI_MM_SX_REGISTER EFI_SMM_SX_REGISTER2;
This service registers a function (DispatchFunction) which will be called when the sleep state
event specified by RegisterContext is detected. On return, DispatchHandle contains a
unique handle which may be used later to unregister the function using UnRegister().
The DispatchFunction will be called with Context set to the same value as was passed into
this function in RegisterContext and with CommBuffer and CommBufferSize set to
NULL and 0 respectively.
@param[in] This Pointer to the EFI_SMM_SX_DISPATCH2_PROTOCOL instance.
@param[in] DispatchFunction Function to register for handler when the specified sleep state event occurs.
@param[in] RegisterContext Pointer to the dispatch function's context.
The caller fills this context in before calling
the register function to indicate to the register
function which Sx state type and phase the caller
wishes to be called back on. For this intertace,
the Sx driver will call the registered handlers for
all Sx type and phases, so the Sx state handler(s)
must check the Type and Phase field of the Dispatch
context and act accordingly.
@param[out] DispatchHandle Handle of dispatch function, for when interfacing
with the parent Sx state SMM driver.
@retval EFI_SUCCESS The dispatch function has been successfully
registered and the SMI source has been enabled.
@retval EFI_UNSUPPORTED The Sx driver or hardware does not support that
Sx Type/Phase.
@retval EFI_DEVICE_ERROR The Sx driver was unable to enable the SMI source.
@retval EFI_INVALID_PARAMETER RegisterContext is invalid. Type & Phase are not
within valid range.
@retval EFI_OUT_OF_RESOURCES There is not enough memory (system or SMM) to manage this
child.
