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.
