ASoC: cs35l56: probe() should fail if the device ID is not recognized

Return an error from driver probe if the DEVID read from the chip is not
one supported by this driver.

In cs35l56_hw_init() there is a check for valid DEVID, but the invalid
case was returning the value of ret. At this point in the code ret == 0
so the caller would think that cs35l56_hw_init() was successful.
