[PATCH] ASoC: simple_card_utils.h: Add missing include

[Daniel Baluta]

When debug is enabled compiler cannot find the definition of
clk_get_rate resulting in the following error:

./include/sound/simple_card_utils.h:168:40: note: previous implicit
declaration of âclk_get_rateâ was here
   dev_dbg(dev, "%s clk %luHz\n", name, clk_get_rate(dai->clk));
./include/sound/simple_card_utils.h:168:3: note: in expansion of macro
âdev_dbgâ
   dev_dbg(dev, "%s clk %luHz\n", name, clk_get_rate(dai->clk));

Fix this by including the appropriate header.
