dt-bindings: sound: cs42l51: Remove unneeded I2C unit name
The following warning is seen with 'make dt_binding_check':

Documentation/devicetree/bindings/sound/cirrus,cs42l51.example.dts:18.15-34.11: Warning (unit_address_vs_reg): /example-0/i2c@0: node has a unit name, but no reg or ranges property

Fix it by removing the unneeded i2c unit name.
