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.

The binding indicates the clock is required. You need to update the
binding to match the code.
