dt-bindings: remoteproc: qcom,adsp: drop resets and qcom,halt-regs
Some remote processors (e.g. QCS404 CDSP, SC7180 MPSS/MSS) can be brought to life using two different bindings: 1. PIL (Peripheral Image Loader) 2. PAS (Peripheral Authentication Service) They still describe the same hardware - firmware load for remote processor - but use different methods to communicate with that processor. For these SoCs, the qcom,adsp.yaml bindings were describing the PAS method, however for easier customization of board DTS, the bindings combined additional properties from PIL: reset lines, qcom,halt-regs and additional clocks. The devices and Linux kernel drivers, when instantiated as PAS, do not use these properties, so drop them from the bindings.
