arm64: dts: ti: k3: Rename rproc reserved-mem nodes to 'memory@addr'

Currently, the reserved memory carveouts used by remote processors are
named like 'rproc-name-<dma>-memory-region@addr'. While it is
descriptive, the node label already serves that purpose. Rename reserved
memory nodes to generic 'memory@addr' to align with the device tree
specifications. This is done for all TI K3 based boards.
