sysfs: Document new "group visible" helpers
Add documentation and examples for how to use
DEFINE_SYSFS_GROUP_VISIBLE() and SYSFS_GROUP_VISIBLE(). Recall that the
motivation for this work is that it is easier to reason about the
lifetime of statically defined sysfs attributes that become visible at
device_add() time rather than dynamically adding them later.
DEFINE_SYSFS_GROUP_VISIBLE() tackles one of the reasons to opt for
dynamically created attributes which did not have a facility for hiding
empty directories.
