spi: spi-s3c64xx.c: Remove of_node_put for auto cleanup
Use the scope based of_node_put() cleanup in s3c64xx_spi_csinfo to automatically release the device node with the __free() cleanup handler Initialize data_np at the point of declaration for clarity of scope. This change reduces the risk of memory leaks and simplifies the code by removing manual node put call.
