remove reference to the obsolete EFI_LIGHT_ISA_IO_PROTOCOL. This protocol is introduced for size reduction. But later this method is obsoleted as EDK II use feature flags to conditional mask off some code. As EDK II core code does not produce this protocol so we remove all reference to this protocol.
