Subject: [PATCH v2] dt-bindings: clock: Convert qcom,lcc to DT schema

Convert the text bindings for the lcc to yaml format. Doing this showed
that clocks and clock-names were not documented, so fix that now.

Changes in v2:
- drop minItems for clocks (as it equals maxItems)
- drop "binding" word from title
