tty: serial: samsung: reduce number of casts
The pointers to instances of "struct s3c24xx_serial_drv_data" are first cast to kernel_ulong_t and then either used directly (in "platform_device_id.driver_data") or cast again to void * (in "of_device_id.data"). One cast can be dropped, so at least for "of_device_id.data" case there will be no casts at all. This makes the code a bit simpler.
