Subject: [PATCH v3 2/5] dt-bindings: soc: qcom: eud: Add SM6115 / SM4250 support

Add dt-bindings for EUD found on Qualcomm SM6115 / SM4250 SoC.

On this SoC (and derivatives) the enable bit inside 'tcsr_check_reg'
needs to be set first to 'enable' the eud module.

So, update the dt-bindings to accommodate the third register
property (TCSR Base) required by the driver on these SoCs.

Also for these SoCs, introduce a new bool property
'qcom,secure-mode-enable', which indicates that the mode manager
needs to be accessed only via the secure world.
