Add properties as per new bindings in zynqmp remoteproc node to represent TCM address and size. This patch also adds alternative remoteproc node to represent remoteproc cluster in split mode. By default lockstep mode is enabled and users should disable it before using split mode dts. Both device-tree nodes can't be used simultaneously one of them must be disabled. For zcu102-1.0 and zcu102-1.1 board remoteproc split mode dts node is enabled and lockstep mode dts is disabled.
