SDX75 diverged from SDX55 due to introduction of separate DTB firmware 
binary and addition of DSM and Qlink logging memory regions. Considering 
these additions, SM8550 PAS bindings seem closest.
Thanks for catching updates required for allOf constraints. I will add 
sdx75 compatible in-line with qcom,sm8650-mpss-pas.
Please let me know if you recommend creating new bindings for SDX75.
