Subject: [PATCH v9 2/7] dt-bindings: soc: qcom: eud: Document vendor-specific 'secure mode' property

On some SoCs (like the SM6115 / SM4250 SoC), the enable bit inside
'tcsr_check_reg' needs to be set first to 'enable' EUD mode.

So introduce a vendor-specific dt-property 'qcom,secure-eud-reg'
which specifies the base address of the TCSR reg space and the offset
of the 'tcsr_check_reg'.
