ASoC: simple-card-utils: Unify clock direction by clk_direction
Original sample-card assumes SND_SOC_CLOCK_IN is used for
snd_soc_dai_set_sysclk(), but someday, Codec uses SND_SOC_CLOCK_IN
and CPU uses SND_SOC_CLOCK_OUT at hw_params(), and dai->clk_direction
is used at simple_init_dai().
There is no uniformity today. Let's use dai->clk_direction for all cases.
Fortunately, almost all DAI doesn't care about "dir"
(= SND_SOC_CLOCK_IN/OUT) in .set_sysclk callback function (which is called
in snd_soc_dai_set_sysclk()), so this patch has no effect in such DAIs.
But this patch might breaks some existing Sound Card. Use
"system-clock-direction-out" property if it needs to use SND_SOC_CLOCK_OUT
