Subject: [PATCH v2 1/4] dt-bindings: clock: qcom: Add CMN PLL support for
 IPQ5424 SoC

The CMN PLL block in the IPQ5424 SoC takes 48 MHZ as the reference
input clock. The output clocks are the same as IPQ9574 SoC, except
for the clock rate of output clocks to PPE and NSS.

Also, add the new header file to export the CMN PLL output clock
specifiers for IPQ5424 SoC.
