power: supply: use sysfs_emit() instead of scnprintf() for sysfs show()
As documented in Documentation/filesystems/sysfs.rst the sysfs
show() function should use sysfs_emit() or sysfs_emit_at() to
format the userspace return value. This replaces all instances
of scnprintf() with sysfs_emit() in the power-supply subsystem.
