ASoC: rsnd: Fix possible NULL pointer dereference

25165f79adc76b812bfb4d8f2ab120aafb28d0e6
("ASoC: rsnd: enable clock-frequency for both 44.1kHz/48kHz")
supports both 44.1kHz/48kHz clock-frequency settings for ADG
which will be used for AUDIO_OLKOUTn.
But some board doesn't need it, thus, it is not mandatory.

But, above patch didn't care about the case of "clock-frequency" DT
property was not present.
This patch ignores ADG settings if AUDIO_OLKOUTn was not used.
