Subject: [PATCH] ASoC: Intel: cht_bsw_rt5645.c: Remove buffer and snprintf calls

From: Damian van Soelen <dj.vsoelen@...il.com>

The snprintf calls filling cht_rt5645_cpu_dai_name / cht_rt5645_codec_aif_name
always fill them with the same string ("ssp0-port" resp "rt5645-aif2") so
instead of keeping these buffers around and making the cpu_dai_name /
codec_aif_name point to this, simply update the foo_dai_name and foo_aif_name pointers to
directly point to a string constant containing the desired string.
