arm64: dts: ti: k3-j7200: Update R5F nodes to use upstream properties

Update all the MCU and MAIN R5F nodes on J7200 SoCs to use the
upstream-friendly property-names compliant with the YAML-format
binding document,
  Documentation/devicetree/bindings/remoteproc/ti,k3-r5f-rproc.yaml

The following properties were substituted:
  lockstep-mode => ti,cluster-mode
  atcm-enable   => ti,atcm-enable
  btcm-enable   => ti,btcm-enable
  loczrama      => ti,loczrama

The driver continues to support legacy property names, but these will
not be supported in a future LTS kernel. Any dynamic fdt fixups or
overlays should migrate to use the newer property names.
