[PATCH] arm64: dts: qcom: shikra: Add RF_CLK2 clock to wcn3988-pmu nodes

[Cheng Jiang]

The WCN3988 on the Shikra SoMs takes its reference clock from the RPM
RF_CLK2 clock. It is not described in the device tree, so pwrseq-qcom-wcn
finds no clock to enable and RF_CLK2 stays off, leaving Bluetooth unable
to come up.

Describe the clock on the wcn3988-pmu nodes in both SoM dtsi files so
pwrseq-qcom-wcn enables it as part of the WCN3988 power-on sequence.
