Subject: [PATCH 2/5] dt-bindings: clock: qcom: Add CMN PLL support for
 IPQ5332 SoC

Add device tree bindings for the CMN PLL block in IPQ5332 SoC, which shares
similarities with IPQ9574 but has different output clock frequencies.

Add a new header file to export CMN PLL output clock specifiers for IPQ5332
SoC.
