ASoC: Intel: cht_bsw_rt5672: Simplify probe() with local 'dev' pointer

In snd_cht_mc_probe(), &pdev->dev is dereferenced repeatedly throughout
the function. Introduce a local dev pointer
early in the function and use it consistently in place of all open-coded
&pdev->dev references.

It reduces repetition, improves readability, and aligns with the common
kernel driver pattern of caching the device pointer at function entry.
