[alsa-devel] [PATCH v3 07/22] ASoC: rt5651: Enable Platform Clock during jack-type detect

When using RCCLK instead of MCLK / PLL1 the OVCD status often gets stuck
at its last value, which breaks jack-type detection.

This commit fixes this by force-enabling the platform clock when doing
jack-type detection.
