@brief Helper function for calloc a DMA capable memory buffer

@param[in] calloc_num Number of elements to allocate @param[in] size Size in bytes, the amount of memory to allocate @param[in] dma_mem_info DMA and memory info, see esp_dma_mem_info_t @param[out] out_ptr A pointer to the memory allocated successfully @param[out] actual_size Actual size for allocation in bytes, when the size you specified doesn’t meet the DMA alignment requirements, this value might be bigger than the size you specified. Set null if you don’t care this value.

@return - ESP_OK: - ESP_ERR_INVALID_ARG: Invalid argument - ESP_ERR_NO_MEM: No enough memory for allocation
