QCOM SM8250 camera subsystem depends on three power domains, at the moment all of them are not differentiated one from another, however the power domains compose a hierarchical structure with vfe0 and vfe1 as subdomains of titan_top, also managing vfe0 and vfe1 separately allows to get more fine-grained power control in runtime. The change should have no implications on any SM8250 CAMSS users, since none of the boards supported in upstream enables the camss device tree node.
