soundwire: intel_ace2x: move and extend clock selection

soundwire: intel_ace2x: move and extend clock selection

The input clock to the SoundWire IP can be
38.4 MHz (xtal clock source)
24.576 MHz (audio cardinal clock)
96 MHz (internal Audio PLL)

This patch moves the clock selection outside the mutex and add the new
choices for 24.576 and 96 MHz, but doesn't add any functionality.
Follow-up patches will add support for clock selection.
