ASoC: simple-card: Drop unnecessary "dai-tdm-slot-width-map" property presence check

It doesn't matter whether "dai-tdm-slot-width-map" is not present or
there is some other issue parsing it in of_property_count_elems_of_size()
causing an error. Drop the presence check and rely on
of_property_count_elems_of_size() error return if not present.
