ASoC: pcm3168a: cleanup unintuitive mask usage
When checking if the requested parameters are supported, the driver uses
PCM3168A_FMT_DSP_MASK to check for PCM3168A_FMT_DSP_* values.
However, formally not only PCM3168A_FMT_DSP_* values match that
condition, PCM3168A_FMT_I2S_TDM and PCM3168A_FMT_LEFT_J_TDM also do.
The check still gives correct result because those extra values can't
be in 'fmt' at the check location. Still, to make the code less cryptic,
better to compare 'fmt' with PCM3168A_FMT_DSP_* values explicitly.
