dai: intel: dmic: demote spurious LOG_ERR in dai_nhlt_get_clock_div()

Fix the log level of two LOG_ERR() statements which should have always
been LOG_INF(). As confirmed by the author Adrian in zephyrproject-rtos#60172

Fixes commit 3fbaed4 ("dai: intel: ace: dmic: Refactor of
dai_nhlt_dmic_dai_params_get function")
