dt-bindings: clock: Add YAML schemas for LPASS clocks on SC7280
PATCH v5 1/2 dt-bindings: clock: Add YAML schemas for LPASS clocks on SC7280
The LPASS(Low Power Audio Subsystem) clock provider have a bunch of generic properties that are needed in a device tree. Also add clock ids for LPASS core clocks and audio clock IDs for LPASS client to request for the clocks.
