For greater compatibility with upcoming kits that will reuse the baseboard
and SOM-level files, adjust the I2C speeds to make it the most compatible
with all devices.

Thanks, all i2c devices on the bus support 400 kHz.
Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>

i.e. will queue in renesas-devel for v5.12.

Gr{oetje,eeting}s,
