Subject: [PATCH V7 1/5] dt-bindings: clock: Add "qcom,adsp-pil-mode" property

The LPASS Peripheral loader clocks would be used to bring
LPASS out of reset, when this property is present.

This is a cleanup done to handle overlap of regmap of
lpasscc and lpass_aon blocks. As a part of this, remove
the "cc" regmap from lpasscc node.
