[v2,1/2] dt-bindings: soc: qcom: eud: Add SM6115 / SM4250 binding

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 required by the driver on these SoCs.

Subject: drop second, redundant "binding".

Is this valid also for sc7280? From commit description looks like not,
so you should have allOf:if:then constraining the items per variant.

So this is going to be a 4 byte region in the middle of the &tcsr block?

Could we instead make that a reference to &tcsr + offset?
