/**
Sends SD command to an SD card that is attached to the SD controller.
The PassThru() function sends the SD command specified by Packet to the SD card
specified by Slot.
If Packet is successfully sent to the SD card, then EFI_SUCCESS is returned.
If a device error occurs while sending the Packet, then EFI_DEVICE_ERROR is returned.
If Slot is not in a valid range for the SD controller, then EFI_INVALID_PARAMETER
is returned.
If Packet defines a data command but both InDataBuffer and OutDataBuffer are NULL,
EFI_INVALID_PARAMETER is returned.
@param[in] This A pointer to the EFI_SD_MMC_PASS_THRU_PROTOCOL instance.
@param[in] Slot The slot number of the SD card to send the command to.
@param[in,out] Packet A pointer to the SD command data structure.
@param[in] Event If Event is NULL, blocking I/O is performed. If Event is
not NULL, then nonblocking I/O is performed, and Event
will be signaled when the Packet completes.
@retval EFI_SUCCESS The SD Command Packet was sent by the host.
@retval EFI_DEVICE_ERROR A device error occurred while attempting to send the SD
command Packet.
@retval EFI_INVALID_PARAMETER Packet, Slot, or the contents of the Packet is invalid.
@retval EFI_INVALID_PARAMETER Packet defines a data command but both InDataBuffer and
OutDataBuffer are NULL.
@retval EFI_NO_MEDIA SD Device not present in the Slot.
@retval EFI_UNSUPPORTED The command described by the SD Command Packet is not
supported by the host controller.
@retval EFI_BAD_BUFFER_SIZE The InTransferLength or OutTransferLength exceeds the
limit supported by SD card ( i.e. if the number of bytes
exceed the Last LBA).
