In the IPA device sysfs directory, the "version" file can be read to
find out what IPA version is implemented. The content of this file
is supplied by ipa_version_string(), which needs to be updated to
properly handle IPA v5.0.

Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.

all such cases.

Create a new attribute group meant to provide a single place that
defines endpoint IDs that might be needed by user space. Not all
defined endpoints are presented, and only those that are defined
will be made visible.
The new attributes use "extended" device attributes to hold endpoint
IDs, which is a little more compact and efficient. Reimplement the
existing modem endpoint ID attribute files using common code.

Add IPA device attributes to expose information known by the IPA
driver about the hardware and its configuration.
All pointers used to display these attribute values (i.e., IPA
pointer and endpoint pointers) will have been initialized by the
time IPA probe has completed, so they may be safely dereferenced.
