snd_pcm_hw_constraint_minmax() may return 1, which is then returned
from rk_aif1_startup(). ASoC only marks the DAI link as started
when .startup() returns 0.

This currently has no functional impact, as there is no .shutdown()
callback in the relevant snd_soc_ops. Still, return 0 explicitly on
success to match what ASoC expects and ensure the DAI link is correctly
marked as started.
