Pretty sure I already asked, but no answer in the commit message. Why do 
we need this? You've already declared the platform supports SCM calls 
with "qcom,scm". Why can't you probe whether you have QSEECOM or not? DT 
is for non-discoverable h/w we are stuck with. Why is software made 
non-discoverable too?

Nodes with only a compatible string are usually just an abuse of DT to 
instantiate some driver.
