[PATCH 4/4] arm64: dts: qcom: Add Mahua QCB

[Sivansh Gupta <sivansh.gupta@oss.qualcomm.com>]

Add initial device tree support for Mahua QCB. Mahua QCB is a variant
of Glymur QCB but using Mahua SoC instead of Glymur SoC.
Mahua is a 12 core derivative of Glymur SoC.

Unlike the CRD, the QCB is suitable for compute workloads, power
measurements and oscilloscope-based hardware validation.

Includes glymur-qcb.dtsi, adds Mahua QCB specific board compatible,
adds tcsr regulator-supply properties, removed cluster2 PMIC/thermal
nodes.
