Store DMA mapping data in geni_i2c_dev struct to enhance DMA mapping data scope. For example during shutdown callback to unmap DMA mapping, this stored DMA mapping data can be used to call geni_se_tx_dma_unprep and geni_se_rx_dma_unprep functions. Add two helper functions geni_i2c_rx_msg_cleanup and geni_i2c_tx_msg_cleanup to unwrap the things after rx/tx FIFO/DMA transfers, so that the same can be used in geni_i2c_stop_xfer() function during shutdown callback.
