In three Intel ASoC board drivers, the EVENT_ON path in
platform_clock_control() enables MCLK using clk_prepare_enable(), but
error paths fail to call clk_disable_unprepare(), leaking a clock
reference.

Fix this by calling a clk_disable_unprepare() on error paths after MCLK
has been enabled.

v2: Guard clk_disable_unprepare() with SND_SOC_DAPM_EVENT_ON() to avoid
callling it in the EVENT_OFF error path where MCLK was never enabled.
