hwmon: (ads7871) Replace sprintf() with sysfs_emit()

Browse Source 
Use sysfs_emit() instead of sprintf() in the sysfs show function
voltage_show() to comply with the preferred kernel interface for
writing to sysfs buffers, which ensures PAGE_SIZE buffer limits
are respected.

No functional change intended.

Note: Not runtime tested due to lack of hardware.
