[PATCH v6 1/4] ASoC: Intel: bytcr_rt5640: Fix MCLK leak on platform_clock_control error

[aravindanilraj0702]

From: Aravind Anilraj <aravindanilraj0702@xxxxxxxxx>

If byt_rt5640_prepare_and_enable_pll1() fails, the function returns
without calling clk_disable_unprepare() on priv->mclk, which was
already enabled earlier in the same code path. Add the missing
cleanup call to prevent the clock from leaking.
