drivers: remoteproc: xilinx: Fix carveout names

commit 81c18e08a609706c5c2887f267135fa0dece4119 upstream.

If the unit address is appended to node name of memory-region,
then adding rproc carveouts fails as node name and unit-address
both are passed as carveout name (i.e. vdev0vring0@xxxxxxxx). However,
only node name is expected by remoteproc framework. This patch moves
memory-region node parsing from driver probe to prepare and
only passes node-name and not unit-address
