i2c: rcar: tidyup priv->devtype handling on rcar_i2c_probe()

rcar_i2c_probe() has priv->devtype operation, but handling (A) and (C)
in same place is more understandable ( (A) and (B) are independent).

(A)	if (priv->devtype < I2C_RCAR_GEN3) {
		...
	}

(B)	...

(C)	if (priv->devtype >= I2C_RCAR_GEN3) {
		...
	}

Let's merge it with if-else
