[PATCH] firmware: stratix10-rsu: replace scnprintf() with sysfs_emit() in *_show() functions

[Rahul Kumar <rk0006818@gmail.com>]

Replace scnprintf() with sysfs_emit() in sysfs *_show() functions
in stratix10-rsu.c to follow the kernel's guidelines from
Documentation/filesystems/sysfs.rst.

This improves consistency, safety, and makes the code easier to
maintain and update in the future.
