staging: greybus: arche-platform: Use sysfs_emit instead of sprintf

Browse Source 
Refactor sprintf to sysfs_emit in the show function of the arche platform
driver. This follows the standard kernel practice of using sysfs_emit for
sysfs attributes, ensuring consistent output formatting and newline
handling.
