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

[ Upstream commit 3b3312f28ee2d9c386602f8521e419cfc69f4823 ]

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.
