Subject: [PATCH v5 8/8] dt-bindings: remoteproc: qcom: sc7280-adsp-pil: Add missing properties

Add reg-names and power-domain-names for remoteproc ADSP pheripheral
loader. Add firmware-name property to distinguish and load different
firmware binaries of various vendors.
Change qcom,halt-regs property phandle to tcsr_1 from tcsr_mutex.
Also add required-opps property and change power domain from LCX to CX,
which is actual PD to be controlled, for setting appropriate
performance state.
This is to make compatible with remoteproc ADSP PIL driver and
latest device tree changes.

Fixes: 8490a99586ab ("dt-bindings: remoteproc: qcom: Add SC7280 ADSP support")
