ASoC: simple_card_utils.h: convert not to use asoc_xxx()

ASoC: simple_card_utils.h: convert not to use asoc_xxx()

ASoC is using 2 type of prefix (asoc_xxx() vs snd_soc_xxx()),
but these are unified into snd_soc_xxx().

simple_card / audio_graph drivers are historically using
asoc_xxx() prefix too. simple_card / audio_graph are not
ASoC framework, so let's use simple_card_xxx_() / audio_graph_xxx()
for global function prefix.

This patch has asoc_xxx() as define to keep compatible.
It will be removed if all drivers were switched to new style.
