[PATCH v2 2/3] ASoC: SDCA: export sdca_asoc_populate_rate_format() helper

[PATCH v2 2/3] ASoC: SDCA: export sdca_asoc_populate_rate_format() helper

[shumingf]

From: Shuming Fan <shumingf@realtek.com>

Export populate_rate_format() as sdca_asoc_populate_rate_format() so that
it can be used by codec drivers.
The codec driver could get rate and format information for the IT/OT entity.
