The xiic driver is designed to operate without explicit clock configuration
when clocks are not specified in the firmware. This functionality is
already implemented in xiic_setclk(), which performs an early return when
either i2c_clk or input_clk are zero:

This condition is satisfied when clocks are missing, as clk_get_rate(NULL)
returns zero, allowing the driver to rely on hardware-configured timing.

...

 	mutex_init(&i2c->lock);
 	spin_lock_init(&i2c->atomic_lock);
 
-	i2c->clk = devm_clk_get_enabled(&pdev->dev, NULL);
+	i2c->clk = devm_clk_get_optional_enabled(&pdev->dev, NULL);

You also need to have

	struct device *dev = &pdev->dev;

in *this* patch.

 	if (IS_ERR(i2c->clk))
 		return dev_err_probe(&pdev->dev, PTR_ERR(i2c->clk),
 				     "failed to enable input clock.\n");
