[PATCH] staging: greybus: gbphy: use sysfs_emit() instead of sprintf()

[ts930@naver.com]

From: Park Tae-sun <ts930@dgu.ac.kr>

The sysfs documentation (Documentation/filesystems/sysfs.rst) recommends
using sysfs_emit() instead of sprintf() in sysfs show() callbacks.

Replace sprintf() with sysfs_emit() in the protocol_id_show() callback.

This follows the standard kernel practice and existing use of
sysfs_emit() in other Greybus sysfs show functions.

No functional change.
