i2c: riic: Move generic compatible string to end of array

Reorder the entry in `riic_i2c_dt_ids` to place the generic compatible
string `renesas,riic-rz` at the end of the array, following the
convention used in other Renesas drivers.

Also, drop the unnecessary comma after the sentinel entry, as it is
not needed.
