/**
 This function provides a hook for IHISI sub-function AH=1Fh and should be implemented to do AP Hook for BIOS.
 Please refer to Insyde H2O internal Soft-SMI interface (IHISI) Specification.

 @param[in]         ApState             denote the start of AP process.
                                        ApState = 0x00, AP terminate. (Before IHISI 0x16)
                                        ApState = 0x01, AP start. (After IHISI 0x10)
                                        ApState = 0x02, Start to read ROM. (Before IHISI 0x14)
                                        ApState = 0x03, Start to write ROM. (Before IHISI 0x15)
                                        ApState = 0x04, Start to write EC. (Before IHISI 0x20)
                                        ApState = 0x05, Before dialog popup.
                                        ApState = 0x06, After dialog close and continue running.

 @retval            EFI_UNSUPPORTED     Returns unsupported by default.
 @retval            EFI_MEDIA_CHANGED   Alter the Configuration Parameter.
 @retval            EFI_SUCCESS         The function performs the same operation as caller.
                                        The caller will skip the specified behavior and assuming
                                        that it has been handled completely by this function.
