Remove unnecessary check in API MmIsBufferOutsideMmValid of StandaloneMmMemLib. The API is used to check if a input buffer is outside MMRAM and inside a valid non-MMRAM range. Previously, the API only checks if the input buffer is overlapped with MMRAM range. In the last commit, we add logic to check if the input buffer is inside valid non-MMRAM ranges reported by the resource HOB. Since the resource HOB only covers valid non-MMRAM ranges, we doesn't need to check if the input buffer is inside the MMRAM anymore. Signed-off-by: Dun Tan <dun.tan@intel.com>
