[PATCH 02/11] ASoC: codecs: pcm3168a: Relax probing conditions

[Cezary Rojewski <cezary.rojewski@xxxxxxxxx>]

On ACPI-based systems with Intel MalibouLake there is no "scki" clock
entry defined. Make that initialization part optional and default to
24.576 MHz rate if not set. The rate is the default for both TI and
Intel devices.
