For diolan, this allows factoring out some code that is now common between if and else. For eg20t, pch_i2c_writebytes is always called with a write in msgs->flags, and pch_i2c_readbytes with a read. For imx, i2c_imx_dma_write and i2c_imx_write are always called with a write in msgs->flags, and i2c_imx_read with a read. For qup, qup_i2c_write_tx_fifo_v1 is always called with a write in qup->msg->flags. For stu300, also restructure debug output for resends, since that code as a result is only handling debug output.
