ASoC: simple_card_utils: remove unused cpus/codecs/platforms from props

simple_dai_props has cpus/codecs/platforms. These pointer were used
for dai_link before, but are allocated today since
commit 050c7950 ("ASoC: simple-card-utils: alloc dai_link
information for CPU/Codec/Platform").
We don't need to keep it anymore. This patch removes these.
