Because it looks neater.
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.

Declare i2c_algorithm structures as const as they are only stored in the
algo field of an i2c_adapter structure. This field is of type const, so
i2c_algorithm structures having this property can be made const too.

Add a basic driver for the Renesas EMEV2 SoC. Based on the driver from
the BSP which was first worked on by Ian, and made ready for upstream by
me.
