 This function provides an interface to do additional VbiosHookCallBack function that are list on 
 OemInt15VbiosFunctionHook array.

 @param[in]         Int15FunNum         Int15 function number.
 @param[in out]     CpuRegs             The structure containing CPU Registers (AX, BX, CX, DX etc.).
 @param[in]         Context             Context.

 @retval            EFI_UNSUPPORTED     Returns unsupported by default.
 @retval            EFI_MEDIA_CHANGED   Alter the Configuration Parameter or hook code.
 @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.
