Subject: [PATCH 6/7] ASoC: mt8365: Remove unused DMIC IIR coefficient
 configuration

Nothing ever calls mt8365_dai_load_dmic_iirc_coeff_table() so the compiler
warns about an unused static function. While it seems likely that something
should be calling the function I don't know what and this is breaking
-Werror builds like allmodconfig so let's just remove it. It can be added
again along with the user.
