Subject: [PATCH 1/2] ASoC: topology: Rename clock_gated to clock_cont in snd_soc_tplg_hw_config

In kernel `soc-dai.h`, DAI clock gating is defined as following:

~~~~
\#define SND_SOC_DAIFMT_CONT		(1 << 4) /* continuous clock */
\#define SND_SOC_DAIFMT_GATED		(0 << 4) /* clock is gated */
~~~~

Therefore, the corresponding field of struct snd_soc_tplg_hw_config should
be inverted compared to the current logic:

clock_count = 1 => SND_SOC_DAIFMT_CONT
clock_count = 0 => SND_SOC_DAIFMT_GATED
