Add open-amp patch 0019 to extend fw_rsc_config with h2r_buf_addr and r2h_buf_addr fields, allowing the host and remote sides to specify buffer physical addresses through the resource table. This enables splitting the shared memory pool into separate regions. Also update open-amp.defs and open-amp.cmake to apply the new patch during the open-amp build process.
