[PATCH 1/2] ARM: DTS: kirkwood-openrd-client: fix audio

Fix audio on kirkwood-openrd-client:

1) The audio-controller was left disabled.

2) The probe fails because cs42l51 is missing #sound-dai-cells.

	/sound/simple-audio-card,codec: could not get #sound-dai-cells for /ocp at f1000000/i2c at 11000/cs42l51 at 4a
	asoc-simple-card sound: parse error -22
	asoc-simple-card: probe of sound failed with error -22

3) The mapping is incorrect:

	asoc-simple-card sound: cs42l51-hifi <-> spdif mapping ok

   should be:

	asoc-simple-card sound: cs42l51-hifi <-> i2s mapping ok
