Subject: [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.
