[PATCH 2/4] ASoC: codecs: si476x: Handle hw_params return value

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

snd_soc_component_update_bits() may return 1 when the register value
changes, but ASoC only marks the DAI hw_params as done when .hw_params()
returns 0.

Propagate negative errors and return 0 on success.
