MdePkg: Reference new definitions for Management Mode.

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.

/**
Register an IO trap SMI child handler for a specified SMI.
typedef EFI_MM_IO_TRAP_DISPATCH_REGISTER EFI_SMM_IO_TRAP_DISPATCH2_REGISTER;
This service registers a function (DispatchFunction) which will be called when an SMI is
generated because of an access to an I/O port specified by RegisterContext. On return,
DispatchHandle contains a unique handle which may be used later to unregister the function
using UnRegister(). If the base of the I/O range specified is zero, then an I/O range with the
specified length and characteristics will be allocated and the Address field in RegisterContext
updated. If no range could be allocated, then EFI_OUT_OF_RESOURCES will be returned.
The service will not perform GCD allocation if the base address is non-zero or
EFI_SMM_READY_TO_LOCK has been installed. In this case, the caller is responsible for the
existence and allocation of the specific IO range.
An error may be returned if some or all of the requested resources conflict with an existing IO trap
child handler.
It is not required that implementations will allow multiple children for a single IO trap SMI source.
Some implementations may support multiple children.
The DispatchFunction will be called with Context updated to contain information
concerning the I/O action that actually happened and is passed in RegisterContext, with
CommBuffer pointing to the data actually written and CommBufferSize pointing to the size of
the data in CommBuffer.
@param[in] This Pointer to the EFI_SMM_IO_TRAP_DISPATCH2_PROTOCOL instance.
@param[in] DispatchFunction Function to register for handler when I/O trap location is accessed.
@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 the IO trap SMI source for which the dispatch function should be invoked.
@param[out] DispatchHandle Handle of the dispatch function, for when interfacing with the parent SMM driver.
@retval EFI_SUCCESS The dispatch function has been successfully registered.
@retval EFI_DEVICE_ERROR The driver was unable to complete due to hardware error.
@retval EFI_OUT_OF_RESOURCES Insufficient resources are available to fulfill the IO trap range request.
@retval EFI_INVALID_PARAMETER RegisterContext is invalid. The input value is not within a valid range.
