i2c: davinci: Unregister cpufreq notifier on probe failure

Browse Source 
davinci_i2c_probe() registers a cpufreq transition notifier before adding
the I2C adapter.  If i2c_add_numbered_adapter() fails, the probe error path
releases the device resources without unregistering the notifier.

Add a dedicated error path to unregister the cpufreq notifier after
i2c_add_numbered_adapter() fails.
