ASoC: rt5640: Do not manipulate pin "Platform Clock" if the "Platform Clock" is not...

The pin "Platform Clock" was only used by the Intel Byt CR platform. In the
others, the error log will be informed. The patch will set the flag to
avoid the pin "Platform Clock" manipulated by the other platforms.
