This patch is to remove legacy SmBase relocation in PiSmmCpuDxeSmm Driver. The responsibility for SmBase relocation has been transferred to the SmmRelocationInit interface, which now handles the following tasks: 1. Relocates the SmBase for each processor. 2. Generates the gSmmBaseHobGuid HOB. As a result of this change, the PiSmmCpuDxeSmm driver's role in SMM environment setup is simplified to: 1. Utilize the gSmmBaseHobGuid to determine the SmBase. 2. Perform the ExecuteFirstSmiInit() to do early SMM initialization.
