[PATCH v3 4/4] arm64: dts: qcom: glymur: Add QREF regulator supplies to TCSR

The TCSR clkref clocks gate the QREF block which provides reference
clocks to the PCIe PHYs. Wire up the LDO supplies required by the QREF
and refgen blocks on the CRD board:

- vdda-refgen_0p9/1p2: LDOs for the refgen block that generates the
reference voltage for QREF
- vdda-qrefrx/tx/rpt: LDOs for the QREF receiver, transmitter
and repeater circuits
