[PATCH] remoteproc: debugfs: Replace scnprintf() with sysfs_emit()

[Abhinav Ananthu]

I apologize for the mistake in the signed-off email address in the previous 
patch.

Convert the debugfs show() functions in remoteproc_debugfs.c to use
sysfs_emit() instead of scnprintf(). The sysfs_emit() helper is the
preferred way to format sysfs output as it ensures the output is
properly bounded to PAGE_SIZE and simplifies the code.

This patch addresses three instances of scnprintf() usage in the file.
