spi: spi-s3c64xx.c: Remove of_node_put for auto cleanup

Browse Source 
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.
