ASoC: simple-card: fixup cpu_dai_name clear case
f687d900d30a61dda38db2a99239f5284a86a309
(ASoC: simple-card: cpu_dai_name creates confusion when DT case)
cleared cpu_dai_name for caring fmt_single_name case,
and
179949bc04c7157a4b2279f62a842638b61f78f9
(ASoC: simple-card: remove dai_link->cpu_dai_name when DT)
cared multi dai-link case.
but, cpu_dai_name matching is required when fmt_multiple_name was used
