Drivers: DAI: Intel: Remove trace from dai_dmic_update_bits()

The dai_dmic_update_bits() function is used in start trigger
code dai_dmic_start() and in capture runtime to control DMIC
IP in unmute sequence. Especially the start sequence is timing
critical so it's better not produce additional delay in this
function.
