arm64: dts: qcom: ipq5332: Add CMN PLL node for networking hardware

Browse source

Add the CMN PLL node required for networking hardware operation on IPQ5332.
The CMN PLL core runs at 6 GHz on this platform, differing from others like
IPQ9574.

Configure the reference clock path where XO (48 MHz or 96 MHz) routes
through the WiFi block's multiplier/divider to provide a stable 48 MHz
reference to the CMN PLL.
.XO (48 MHZ or 96 MHZ)-->WiFi (multiplier/divider)--> 48 MHZ to CMN PLL.
