Document the clock property in sc7280 LPASS LPI pinctrl node.
Clock settings required for Audioreach solution.

The existing SC7280 platform only supports non-ADSP audio solutions.
To enable audio functionality on ADSP with the AudioReach solution.
additional core and audio hardware clocks must be configured.
Without these clocks, the ADSP will crash.
