Convert Texas Instruments keystone PSC clock binding to DT schema. The vendor-specific 'domain-id' property is intentionally kept without a "ti," prefix to preserve existing ABI since driver and existing board file use property without "ti," prefix.
Also update the reference to this binding in ti,keystone-rproc.txt to point at the new filename.
