1089** Description      Set Host-to-NFCC NCI message size for secure patch download
1090**
1091**                  This API must be called before calling HAL_NfcPrmDownloadStart.
1092**                  If the API is not called, then PRM will use the default
1093**                  message size.
1094**
1095**                  Typically, this API is only called for platforms that have
1096**                  message-size limitations in the transport/driver.
1097**
1098**                  Valid message size range: NFC_HAL_PRM_MIN_NCI_CMD_PAYLOAD_SIZE to 255.
1099**
1100** Returns          HAL_NFC_STATUS_OK if successful
1101**                  HAL_NFC_STATUS_FAILED otherwise
