/*******************************************************************************
**
** Function         HAL_NfcPrmSetSpdNciCmdPayloadSize
**
** Description      Set Host-to-NFCC NCI message size for secure patch download
**
**                  This API must be called before calling HAL_NfcPrmDownloadStart.
**                  If the API is not called, then PRM will use the default
**                  message size.
**
**                  Typically, this API is only called for platforms that have
**                  message-size limitations in the transport/driver.
**
**                  Valid message size range: NFC_HAL_PRM_MIN_NCI_CMD_PAYLOAD_SIZE to 255.
**
** Returns          HAL_NFC_STATUS_OK if successful
**                  HAL_NFC_STATUS_FAILED otherwise
