[PATCH v2 -next] ASoC: simple-card-utils: remove set but not used variable 'dai_name'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

sound/soc/generic/simple-card-utils.c: In function 'asoc_simple_parse_clk':
sound/soc/generic/simple-card-utils.c:164:18: warning:
 parameter 'dai_name' set but not used [-Wunused-but-set-parameter]

It's not used since commit 0580dde59438 ("ASoC: simple-card-utils: add
asoc_simple_debug_info()"), so can be removed.
