Subject: [PATCH v2 2/9] dt-bindings: clock: Add SM8550 TCSR CC clocks

Add bindings documentation for clock TCSR driver on SM8550.

Signed-off-by: Abel Vesa <abel.vesa@...aro.org>

Changes since v1:
 * based on recent bindings, like Krzysztof asked
 * used qcom,gcc.yaml and dropped redundant properties
 * used additionalProperties instead unevaluatedProperties
 * renamed qcom,tcsrcc-sm8550.h to qcom,sm8550-tcsrcc.h, to match
   compatible
 * added dual lincese to qcom,sm8550-tcsrcc.h
 * moved patch to the beginning of patchset
 * dropped redundant "bindings" from subject line
