ASoC: simple-card: use asoc_simple_card_clk_xxx()

Current simple-card-utils sets asoc_simple_dai::clk via
asoc_simple_card_parse_clk().
Current simple card drivers are using it directly for
clk_enable/disable.
Encapsulation is one of simple card util's purpose.
Let's use asoc_simple_card_clk_enable/disable.
