  ## Pcd8259LegacyModeMask defines the default mask value for platform. This

  #  1) If platform only support pure UEFI, value should be set to 0xFFFF or
  #     0xFFFE; Because only clock interrupt is allowed in legacy mode in pure
  #     UEFI platform.
  #  2) If platform install CSM and use thunk module:
  #     a) If thunk call provided by CSM binary requires some legacy interrupt
  #        support, the corresponding bit should be opened as 0.
  #        For example, if keyboard interfaces provided CSM binary use legacy
  #        keyboard interrupt in 8259 bit 1, then the value should be set to
  #        0xFFFC.
  #     b) If all thunk call provied by CSM binary do not require legacy
  #        interrupt support, value should be set to 0xFFFF or 0xFFFE.
  #
  #  The default value of legacy mode mask could be changed by
  #  EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely need change it
  #  except some special cases such as when initializing the CSM binary, it
  #  should be set to 0xFFFF to mask all legacy interrupt. Please restore the
