perf: Use device_show_string() helper for sysfs attributes
Deduplicate sysfs ->show() callbacks which expose a string at a static
memory location. Use the newly introduced device_show_string() helper
in the driver core instead by declaring those sysfs attributes with
DEVICE_STRING_ATTR_RO().
No functional change intended.
