From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>
Current simple/audio scu card drivers are supporting same
convert-rate/convert-channels on DT, but, doesn't use same function
for it.
Encapsulation is one of simple card util's purpose.
Let's use asoc_simple_card_parse_convert/asoc_simple_card_convert_fixup
