arm64: dts: qcom: mahua: Add QREF regulator supplies to TCSR

Browse Source 
Mahua has a different QREF topology from Glymur. Override the TCSR
compatible to qcom,mahua-tcsr in mahua.dtsi, and wire up the required
LDO supplies on the CRD board.

Unlike the other PCIe controllers, PCIe5 PHY on Mahua gets its refclk
from the CXO0 pad directly and requires no QREF clkref_en voting. Hence,
point its ref clock at RPMH_CXO_CLK.
